According to the Telegraph, the NHS is witnessing a rise in phone calls due to flu and stomach bug epidemic. This is due to the fact that no epidemic has hit us in while and that our general immune system has weakened (not saying that you fellow runners have a weak immune system, I meant the others! lol). The Telegraph also posted a good article about how to boost our immune system (sorry but neither jogging nor booze was mentioned ;-) ). If you are interested have a look to the article called: "Norovirus: be prepared".
