Because the majority have a poor diet and dont exrecise either enough or at all....

Look in the chilled fresh veg section of any supermarket now and you'll find mashed potato, mashed swede, peeled & sliced or diced carrots etc etc etc. I must admit to occasionally buying mashed potato & swede but that's only because Morrison's have knocked it down to £0.09p and it would cost more in gas to boil the spuds.

You'll lose your skills. Then, they'll up their prices to nine quid and you'll be stuffed.
