I've been pondering this for a while. Do you not think that the government should include in it's health education programme, the fact that if children do not get enough sun light and stay in doors playing with game machines and computers too much they could end up with diseases such as MS and R/arthritis. Or perhaps all of our children should have vitamin d included in their foods (as has been suggested for Scotland). I do not live in Scotland but Kent in the SE of England and as far as I remember had quite a bit of sunshine in my youth and played outdoors, such was common in the 1960s. We have quite a lot of MS in my small town by the way. I belive it this is true, rather than looking for cures we should also be trying to prevent these diseases.
