Wimbledon: normal service is resumed

WimbledonDiary date: 2nd July, 1985

If my diary has it right, I think I may have watched more of the 1985 Wimbledon Lawn Tennis Championships than I have of any tournament since – including the one that’s happening right now.

The reason? I was waiting.


The first year of my course in French and Scandinavian Studies had come to an end and I was about to head off for the Summer to work as a cleaner on a Gothenburg dockyard. While I waited anxiously for departure day and the trip to Harwich to catch the ferry, I sat mesmerised by the goings-on in SW19 and tried not to think about how little Swedish I could actually speak.

Somehow, that little patch of grass in London was like a haven of stability just as everything was about to change – reassurance that things would turn out for the best.

So, in honour of the hallowed turf that helped keep my nerves at bay, here are five Wimbledon men’s service-related facts of the kind that might have kept me occupied for at least a minute or two of my maiden voyage across the North Sea.

Meanwhile, I’m off to catch that ferry.

1. Height equals speed

As a top player, more centimetres in height generally equals more speed on your serve. In fact, the link is so strong that an analysis of Wimbledon statistics from 2009 showed that the height of a player in centimetres is almost exactly equal to his average first service speed in kilometres per hour!

2. Aces high

More aces are served in the men’s singles at Wimbledon than at any other slam tournament – the US Open comes next, then the Australian, then the French. Between 1990 and 2009, the number of Wimbledon aces shot up from about 1,900 to around 2,900. The number of aces per tournament has grown steadily at all the other slams too.

3. Speedy slams

In 1999, the average men’s first service speed at Wimbledon was about 15 mph faster than at the French Open. But by 2009, things had evened out, and the average first service speed at all four grand slam tournaments was almost the same at around 116mph. The record for the fastest serve ever at Wimbledon belongs to Taylor Dent and stands at 148mph.

4. Falling  faults

Despite the general increase in service speeds – particularly at the Australian, French and US Opens – the number of double faults has fallen sharply in recent years. In 2001, the double fault count at Wimbledon was about 1,600. By 2007, it had halved to about 800.

5. Second try

The average men’s second service speed has been steadily increasing since 2000 in all Grand Slam tournaments except Wimbledon, where it has remained relatively steady at about 97 mph.

Just for the record, while I was waiting for my slow boat to Gothenburg back in 1985, Boris Becker beat Kevin Curren to win his first ever Grand Slam title, and in the Ladies’ final, Martina Navratilova beat Chris Evert-Lloyd.

From Baby Boomers to the Boomerang Generation

Australian boomerangDiary date: 4th April, 1985

Back in 1985, I’m home from university for a couple of weeks and looking forward to seeing old schoolfriends again. My time off is spent in a blur of sport, reading, socialising and alcohol. These days, I’d be exhausted just thinking about it. But when my diary reaches the end of the holiday, I’m lamenting the lack of excitement, and reflecting that even though I only left my family for the first time a few short months ago, the break is already permanent. I already know that I won’t live at home again.

Fast forward to today, and no matter what your preference, your choice might not be quite so clear cut. According to the UK Office for National Statistics, the number of adult children living at home with their parents has increased by 20% since the end of the nineties – with limited job prospects, stagnating incomes, rising accommodation and living costs, student (and other) debts, and relationship issues all playing their part.

As usual when something like this comes along, we’ve been busy inventing new names for what’s happening – largely as a means of pretending that we’re more in control of it than we actually are.

The winner so far is almost certainly the idea of the ‘Boomerang generation‘ – in which children leave home only to return to live with their family a few years later – which has the advantage of being a ready-made throwback to the original ‘Baby Boomers.’  The more folksy-sounding ‘twixters‘ has been mooted (originally by Time Magazine) but has never quite caught on, despite spawning an indie TV series of the same name. Then there are the usual silly acronyms such as the Yuppie-derivative, ‘Yuckies‘ (Young Unwitting Costly Kids), and the even more outlandish ‘Kippers‘ – Kids In Parents’ Pockets Eroding Retirement Savings – which was coined by the Prudential in 2003.

In Germany, young adults still living at home may find themselves labeled ‘Nesthocker,’ (young birds that stay in their nest for a long time) and are said to be living at ‘Hotel Mama’ – a similar idea to the British ‘Bank of Mum and Dad.’

In Italy, Tommaso Padoa-Schioppa – considered one of the founding fathers of the European single currency – caused a stir in 2007 by referring to stay-at-home children as ‘Bamboccioni‘ – conjuring up an image of clumsy, overgrown babies unable or unwilling to make decisions for themselves.

In Japan, the language sounds even less kind. A variety of cultural and economic factors have resulted in a large constituency of what have become known as parasaito shinguru –  Parasite singles.’

Whichever names eventually stick, given the scale of the changes since last-minute Baby Boomers like me flew the nest, it seems unlikely this shift is going to be reversed anytime soon.
