Sir,

The article on Keeping Well This Winter by Dr. Jewell was great.

But in answer to the question preventing coughs and colds, he missed one very important thing - thoroughly washing your hands before eating and in particular after using the toilet.

I read a few years back about an experiment conducted on the Canadian Navy men. The group that thoroughly washed their hands never had a cold, but the other group did.

So I experimented! My husband, myself, and my 90-year-old mother have not had a cold for over 18 months - try it works.

Senior citizen, Tenby.
