How does track cycling work?

March 7th, 2017 | Sport

Did you experience a little confusion when watching the Olympic action at the velodrome last year? I certainly did. So I looked it up. Here are the ins and outs of track cycling.

Road cycling is pretty straight forward. People start at one point and then try and ride to the other point as fast as they can. The one who gets there first is the winner. Things get slightly more complex when there are stages and time trials, but the basic idea remains the same.

This is not so with track cycling. There are different disciplines and whole new skills to be learned with each one. This guide takes you through the most popular.

It’s all about the slipstream

Much like road cycling, being at the front is hard work. You have to move all of the air out of the way. In comparison, if you are sat behind another rider, it is much easier because you can cruise behind in their slipstream. This is critical throughout track cycling.

Team pursuit

In team pursuit, each team has four riders that have to complete a distance of 3km. Each member of the team will take it in turns to ride at the front, doing most of the work, before falling to the back and allowing the next member to take up the strain.

Only three riders need to finish the race. In theory, the team could go the entire race with all four riders. However, often one rider simply cannot keep up with the pace. Or, more often, the team will work tactically so that one rider does an extended spell at the front, burning all of their energy, before allowing the remaining three to finish the race.

Sprint

Spring is a competition between two individual riders. Distances vary but is often three laps of the track. In sprint races, you will often find the riders going very slowly for the first lap or two. The reason is that if the riders went off fast, the rider at the back would tuck into the front rider’s slipstream, save their energy, and then pass them on the final lap.

To prevent this, the front rider will cruise around at a walking pace, waiting for the perfect moment to strike. They will then suddenly rush off, hoping to catch the other ride unprepared. The other ride attempts to keep close enough to perform the undertake, often riding around the top of the track so they can rush down for a sudden gain of speed.

Keirin

Kieran is a race of 2km. However, for the first three-quarters of the race, the riders follow an electric bike around the track and must keep behind. The bike gradually increases in speed before pulling off the track near the end of the race, at which point it is a free-for-all.

Omnium

Omnium is the heptathlon of the track cycling world. Riders compete in a series of different races including pursuits, elimination races and time trials. An elimination race is a simple race around the track where the rider at the back is eliminated each lap until a winner is found. Omniums will typically end in a points race. This could be over 100 laps, with points given every 10 for the first four riders.

Will Rocksmith teach you to play guitar?

March 6th, 2017 | Music

If you have ever wanted a real-world version of Guitar Hero, Rocksmith may be for you. However, learning guitar still takes a lot of practice.

Guitar Hero has proved to be a very popular game, and it was only a matter of time until people started asking “is there any way this could be done with a real guitar?”

The answer was yes, in the form of Ubisoft’s Rocksmith. You plug a guitar into your games console using a USB to 1/4” jack cable and then play a Guitar Hero-style game, with the idea of it teaching you to play a real guitar.

But does it actually work? I took Ubisoft up on their 60 day challenge: put in an hour per day and you will play guitar for life, or so they say.

Did it work? Sort of. On the positive side, I can indeed play guitar. Within a year or so of first picking it up I was good enough to join a band, if only to hold down some chords while the real guitarists played the fancy stuff.

On the flip side, it really takes practice. I played for two hours per day, instead of one. I also acquired a guitar teacher for one-to-one lessons and still it was really six months before I could play a simple song.

That ignores the fun I had using Rocksmith though. You are playing your favourite tunes, even if it is just the occasional note at first, and while the adaptive difficulty can be annoying at times, it does make it accessible to everyone. Even if it doesn’t turn you into a guitar player for life, you may find you have just as much fun playing it as any other video game.

How to make fried rice

March 5th, 2017 | Food

Want to turn a normally healthy food into something unhealthy and delicious, without having to go down to the local takeaway? Follow these instructions.

Fried rice is super-tasty and really simple to make. It works well as a side dish, or as the main event, especially if you are adding some protein into the mix.

Ingredients

  • Long-grain rice
  • Bean sprouts
  • Garden peas
  • Groundnut oil
  • Egg

Instructions

  1. Pre-cook the rice. The instructions on the packet will explain how to do this will be on the side of the packet. Typically it will involve bringing a pan of water to boil and dropping the rice in for 10 minutes.
  2. Drain the rice and set aside.
  3. Heat a tablespoon of oil in a wok until it is nice and hot.
  4. Throw in the beansprouts and garden peas and stir fry them. By stir fry, I mean push around the pan a lot with a wooden spoon.
  5. Throw the rice in too and give it another two minutes.
  6. Make a hole in the centre of the pan, then crack and egg and drop the contents into the hole.
  7. Give the egg a minute or two to cook, then rough it up with a fork until it is lots of little pieces.
  8. Mix everything together and serve.

Is fresh yeast better than dried yeast?

March 4th, 2017 | Food

Buying, storing and using fresh yeast can be rather time-consuming. But does it produce better bread?

Some cookbooks will insist that you simply cannot bake nice bread without making your own sourdough and using fresh yeast. Others, such as the River Cottage Handbook: Bread says that using fresh yeast is too much hassle most of the time. But what is the truth?

The biggest advantage of dried yeast is that it stays alive for a really long time. A packet may have a shelf live of 6 months or longer. In comparison, fresh yeast needs to be bought when you need it. It will stay alive a little while in the fridge, or you can freeze it, but then you need to remember to defrost it in advance of using it.

You also need to find it. None of the major supermarkets stocks it so you need to find a friendly baker or local health food shop and make an additional trip there to get it. The tried stuff just sits in your cupboard, ready to go.

How about the taste, though? Surely that makes it all worthwhile. Well, in reality, probably not. When I tried both, I could not tell the difference between the bread I had baked with fresh yeast and the bread I had baked with instant yeast.

This is surprising because you would think that I would get at least a placebo benefit from the fresh yeast. But there really is little to choose between the two, at least in bread, you make in your own kitchen.

Fresh yeast might be nice to try once in a while. However, it is unlikely you will notice any difference, and the additional complication makes it a lot of effort for little gain.

Are premium nappies worth the money?

March 3rd, 2017 | Family & Parenting

With most products you can find in the shops, there are premium brands and supermarket brands. Is it worth paying the extra money for? It varies from product to product, but often the answer is no. Can you tell the difference between Kellogg’s corn flakes and supermarket corn flakes? My guess is that if you did not have the box there in front of you, you couldn’t.

Sometimes, the supermarket own brand products are made by the premium brand companies and simply re-packed. This is not always true, though: some products there is a measurable difference and the only way to work it out is to try them. Bare in mind though that there is also the placebo effect. You may think something tastes better simply because you paid more for it. It is clear that people cannot tell the difference between cheap and expensive wine for example.

But what about nappies?

According to the independent consumer magazine Which, the answer is yes and no. Based on their surveys, Pampers do indeed come top being rated as the best nappies you can get. However, they do not score well in one category: value for money. In comparison, some supermarket own brands, including Aldi, score almost as well while being much, much cheaper. How your supermarket fares depends on where you shop: see Which Magazine for full details.

My personal experience mirrors the findings of Which. Pampers are great: they have a wetness indicator on the front and the mesh lining inside them means the waste seeps through while Venla’s bottom is given a bit more protection. For us, it is worth the extra £3 a week we spend to upgrade.

It may come down with how much you want to spend. The premium brands do seem to be slightly better, but for the increased cost means that it is certainly worth trying the cheaper versions first.

How to write a good eulogy

March 2nd, 2017 | Public Speaking

Writing the perfect eulogy is a tough business, especially when you want to do justice to a loved one. These tips will help guide you in the delicate task.

Writing and delivering a eulogy is rarely a pleasant thing to do. However, when you are called upon to do it, chances are you will want to do the best job you can do in honouring the loved one you have lost. You rarely get extended notice, so it is best to be prepared. Here are some tips.

It’s not a biography

The structure of a eulogy will typically talk through a person’s life. This is a good guide for how to lay out your speech. However, it is important to remember that it is not a biography. Everyone at the funeral is likely to have known the person and their life story, so there is no benefit in parroting it back to them. Instead, you should concentrate on distilling the essence of their personality. Pick out a few bits to talk about that really show what kind of person they were.

Unless they were a complete bastard, in which case you should show a mix of their personality. There is no point denying their faults but focus on their good points also.

Use humour

At my public speaking club, I’m noted for adding humour to any situation. In fact, I used to joke that I thought it was always appropriate, though I hadn’t had a eulogy to try it out at yet. That was years ago, and now I have had a eulogy to try it out at, and still stick by my conviction.

Humour is a wonderful tool for keeping people engaged and breaking the tension. it can bring the mood of a room right up. You might think that a funeral is not the place for a eulogy, but I could not disagree more. You need to use humour to lighten the mood not just in spite of it being a funeral, but because of it. You want to leave attendees with a positive memory of the deceased, not a solemn downcast version.

Tell stories

This goes for any speech, ever. Stories have an emotional attachment. People will quickly forget what you said, but how you made them feel will stick around much longer. Humans love stories. So skip the boring details and lay out your speech out hopping from story to story.

If another member of the family has a lovely story about the deceased, invite them up to give it.

Why I got plenty of sleep during Elina’s labour

March 1st, 2017 | Family & Parenting

Sleeping might seem like the last thing you should be doing when your wife has gone into labour. But there is a good reason to get some rest.

She has gone into labour, while you are snoring your head off in the bed next to her. Something wrong? You might think you should be awake to support her, but there is a good reason for you to be asleep.

Millions of years of evolution have made mammals pretty good at giving birth. Like breathing, most of it happens automatically. Hormones pulse around your body, directing your emotions and subtlety controlling your behaviour.

One of the hardest things about labour is not the pain itself, it is the sheer exhaustion of the whole thing. You can be in labour for days, with little or no sleep, and yet somehow women find the strength to go on. They do so because their body makes sure they do, injecting careful amounts of oxytocin and adrenaline at the required times.

Birth partners do not have the benefit of this of course. Things have changed a lot in the past 50 years. We are no longer in the waiting room with a cigar; now we are at our partner’s side helping her through the birth. Mother Nature has not cottoned on to this, though, and leaves us with a few vicarious hormones at best.

So, after 72 hours of sleep deprivation, exactly how helpful are you going to be as a birth partner? This is an important question because when your partner reaches transition, she is going to rely on your support to get through it. If you are barely functioning because you have had no sleep, you are not going to be in a great shape to do that.

Sleeping through half of the labour might seem a selfish thing to do. In reality, though, a somewhat rested birth partner is going be to able to offer far more support than one who is utterly exhausted.

How to support your wife when she wants an active birth

February 28th, 2017 | Family & Parenting

Waiting for the labour pains with a well-timed “I told you so” might seem like a good idea, but turns out not to be if you like your balls attached to your body.

The active birth movement has now been going for 50 years and is almost certainly here to stay. That makes sense. Research suggests that active birth reduces the number of complications and interventions, and allows the mother to recover quicker.

As with everything in pregnancy, though, there are benefits and there are also drawbacks.

First, labour can be really painful. It varies from person to person and from birth to birth, but often the amount of pain management required is going to be dictated by the situation.

Second, not everything goes to plan. So you may be planning to have an active birth but the situation could change quickly if there are any issues with labour. Therefore it is important to go in with a mindset of being ready to adapt to the changes required.

How should you handle it? The most important step is to be supportive. Active birth offers a lot more chance for the father to be involved, supporting your partner through the process and helping with non-drug based pain relief (such as massage, and helping her in and out of the bath).

It is also important to be supportive if things to not go to plan. If she decides she does need pain relief after all, remember to reassure her that almost everyone does, and there is no “failure” in resorting to it.

Overall, active birth is a great decision, especially for dads. The advantage is the reduced chance of intervention, and the disadvantages of additional pain are only felt by the father vicariously.

Why age disparity in relationships matter

February 27th, 2017 | Religion & Politics

On average, men choose to marry women slightly younger than they are. But for would-be dads, this can have a profound impact on family life.

Most people enter relationships with people of a similar age. In western culture this is normal, and indeed doing anything other than this is considered abnormal. However, in different cultures, and at different times, this as not always been the case.

If we look at the 2013 US survey data, we find that a third of heterosexual married couples are within one year of each other. It is not an equal curve on each side though. Women are far more likely to marry older men. In 20% of marriages the man is 2–3 years old, and in 13% 4–5 years older. Compare this to 7% and 3% for women being older.

This makes sense. OK Cupid data, as documented in the book Dataclysm shows that men prefer younger women, and up until the age of 30, women prepare a slightly older man. As many relationships are formed before the age of 30, the older man younger woman setup is likely to have the broader appeal to both parties.

Why is it important, though?

I think it is important because it contributes to the imbalance of women staying at home to look after the children while men continue working. For would-be stay-at-home dads and passionate career women, this is not a desirable situation.

People who are further along in their career earn more money. Nothing controversial there. This means that if you enter into a relationship with someone a few years older than you, on average, they are going to earn more money than you.

When it comes to starting a family, it would be nice to think that childcare could simply be divided as you see fit. However, this is simply not the reality that most of us live in. Many of our decisions are driven by economic factors. That is to say, there are bills to pay and we need to earn enough money to pay them.

Therefore, when it comes to starting a family, many people are faced with the decision of giving up the father’s wage or giving up the mother’s. Unfortunately, for many would-be full-time dads, giving up their own higher wage is not financially viable for the family.

Exactly what can be done about this, I am not sure. You could say that if you want to be a stay-at-home-dad you should marry someone older, or in a more lucrative career than you. However, as most of us know, love does not work that way.

Will suicide nets stop jumpers at the Golden Gate Bridge?

February 26th, 2017 | Health & Wellbeing

When it comes to stopping people throwing themselves off the bridge, the question is, can a one-time intervention really save lives?

When thinking of iconic places to take a suicidal jump from, the Golden Gate Bridge in San Francisco has to come pretty high up that list. In fact, 1,6000 have jumped to their death from the bridge since it opened. It is a fairly reliable way to do it. In that time 26 people have survived, a 98.4% “success” rate.

Now the Golden Gate Bridge are spending nearly £60,000 on installing suicide prevention nets. These wire nets will hang below the bridge, in an attempt to mostly hide them from public view, and be made of steel. It is not going to be a pleasant fall, but should at least save the life of the jumper.

But will it actually work?

According to The Bridge Rail Foundation, a group that has long been campaigning for suicide deterrents to be installed, there is no question that they will help the situation.

They argue that it is simply not the case that once someone has decided to take their own life, nothing can be done to stop them. In fact, most people who fail to take their own life do not try again. 90% of those who are stopped before they can jump go on to live our their remaining lives without suicide. This is a high suicide rate compared with the general population but suggests that intervening once is overwhelmingly successful in keeping people alive.

Experience from around the world suggests they will be effective as well. A similar scheme in Bern, Switzerland was put into place for bridges and city cathedral. Since the nets were installed at the later, nobody has decided to risk the jump. Since 1998 the only creatures to be pulled out of the nets were two dogs. Presumably, they ran over the ledge by accident.
