Doctors in Britain are warning of an obesity time bomb, when children who are already overweight grow up．So, what should we do? Exercise more? Eat less? Or both? The government feels it has to take responsibility for this expanding problem．
The cheerful Mr．Pickwick, the hero of the novel by Charles Dickens, is seen in illustrations as someone who is plump and happy．In 18th century paintings, beauty is equated （使…等同） with rounded bodies and soft curves．But nowadays being overweight is seen as indicating neither a cheerful character nor beauty but an increased risk of heart disease, stroke and diabetes．
So what do you do? Diet? Not according to England's chief medical officer．Sir Liam Donaldson．He says mat physical activity is the key to reducing the risks of obesity, cancer and heart disease．And the Health Secretary John Reid even said that being inactive is as serious a risk factor in heart disease as smoking．
So, having bought some cross trainers, how much exercise should you do? According to Sir Liam Donaldson, at least 30 minutes of moderate activity five days a week．Is going to the gym the answer? Luckily for those who think that running machines are boring, me Health Development Agency believes that physical activity mat fits into people's lives may be more effective．They suggest taking the stairs rather than the lift, walking up escalators, playing active games with your children, dancing or gardening．And according to a sports psychologist．Professor Biddle, gyms "are not making the nation fit", and may even cause harm．
There's new scientific evidence that too much exercise may actually be bad for you．Scientists at the University of Ulster have found that unsuitable exercise releases dangerous free radicals that can adversely （opposingly） affect normal function in unfit people．The only people who should push their bodies to that level of exercise on a regular basis are trained athletes．
So, should we forget about gyms and follow some expert's advice to reduce sedentary （久坐不动的） activities and increase exercise in our daily life? After all, getting off the bus a stop early and walking the rest of the way can't do any harm! One final thought How come past generations lacked gym facilities but were leaner and fitter than people today?

In June 1977, a baby girl became seriously ill in Deleville. Doctors there were unable to find out the cause of her illness, so she was sent to a famous hospital in London, where there were many excellent doctors. The baby was so seriously ill that a team of doctors hurried to examine her without delay. The doctors, too, were puzzled by the baby’s illness and they also became discouraged. Just then a nurse asked to speak to them.
“I think the baby is suffering from thallium (铊) poisoning. ” said the nurse. “A few days ago, I read a story ‘A Pale Horse’ written by Agatha Christie. Someone uses thallium poison, and all the symptoms (症状) are written in the book. They are exactly the same as the baby’s.”
“You’re very good at observing things,” said a doctor, “and you may be right. We’ll carry out some tests and find out whether the cause is thallium poisoning or not.”
The tests proved that the baby had indeed been poisoned by thallium. Once they knew the cause, the doctors were able to give her correct treatment. The baby soon got well and was sent back to Deleville. A week later it was reported that the poison might have come from an insecticide (杀虫剂) used in Deleville.
