Smoking may be bad for your health

Two of my house mates are also doing the 10k, one of whom only started training on monday. "the fool!" i cried, smug in the knowledge i wouldn't be the worst prepared athlete in the field. He came for a run with me on monday night, saying he probably wouldn't keep up. I made lots of reassuring comments to him but secretly saw it as my chance to show him how far he had to come. 5 km later, i was purple with exhaustion whilst he'd barely broken sweat. The fact he's an ex-squaddie is some small consolation, but i think his limited drinking, non-smoking lifestyle has more to do with it. I'm utterly demoralised. And in need of a fag to cheer myself up.
