I'd like to know more about the long-term effects of eating rubbish too, and considering the amount of pappy frozen pizza, cup-a-soup, cakes and Vesta meals that I poured down my throat in my days as a latchkey kid, I sincerely hope that any damage is reversible! It should be - after all, a few years of smoking in the teens has been shown not to make any difference to the future risk of smoking-related diseases.
The combination of junk food and no exercise, and the fact that harmful eating and lifestyle habits are often acquired in the family and persist into adult life, are probably problems. And those pesky thrifty genes, of course.
I have to take some personal responsibility for the Pot Noodle habit. I've encouraged noodle-eating from an early age (Ivor and Tinkerbell still think spaghetti bolognaise is finger food), I voluntarily take Kevin to the shops with me (strange kid - loves the big weekly food-shop), and if I refused to buy the things she couldn't eat them. On the other hand, how many non-vegetarian 11-year-olds will cross the road to avoid a burger bar?
Glenn, all the Grateful Dead fans I know are splendid people. It was a compliment!
