Sport Today

I subscribe to a weekly health and fitness email  by a guy called Ray

he wrote a very good piece about homocysteine levels which was fairly
new to me and I found it very helpful. I've reproduced the whole email
in my blog if you want to take a look.

Is this something which anyone is familiar with and can give a bit of
guidance on? Ta.
