the prevarications of scientists paid by vested interests to discover this or that do not concern me
You clearly know nothing about how science works. A lot of research is paid for by companies, but a lot isn't. Who do those people who advise you to eat more fruit and veg work for? Birds Eye? Fyffes? I too am almost immune to low-grade illnesses, am very warm blooded and I don't eat a lot of fruit and veg. I used to eat hardly any and I still wasn't ill. But I am not conceited enough to think that because of this I know more than those who've been researching physiology since I was in nappies. I just consider myself lucky.
If you actually use your brain, you'd understand that we are talking about RISKS here. So a poor diet increases the RISK of certain things. It doesn't mean you are definitely going to be ill, or die early, or whatever. It goes back to a very well-worn argument that often comes out - everyone knows someone who lived to be 95 and smoked 20 a day. Does that mean that smoking doesn't really cause cancer? No, it doesn't. Because when you look at a larger sample, you will see that lots and lots of people DO get lung cancer who smoke.
I've been studying this, and wearing the minimum clothing consistent with marginal decency this winter, with no ill effects so far.
Again, you might be able to do this but lots of people aren't. So either they are snivelling weaklings under the influence of winter clothing manufacturers' marketing, or we are all made differently. Which is more likely?
I am a generous type, and I want to be nice to people and have them like me. I'm sure I'd get along with you in real life Simon and I don't bear you any animosity but sometimes, you are a prize tw*t. One of the main reasons for this is that you just don't listen to what other people say. Not properly. You have your own little ideas and think that (maybe because you're blessed with some intelligence as well as a strong constitution) you're always right. But true intelligence starts with the ability to know what you don't know.
