Thanks
I'll add to your anecdotal evidence: I have gotten sick less over the last 2 cold/flu seasons, which coincides with when I started to commute daily to/from work by bicycle. I got 1 mild cold last year but none so far this year. Like buzzman posted, I have felt myself stave off colds/flu(?) a couple of times since late fall.
Not sure anyone knows how much exercise boosts the immune system, but if you are alone on your bicycle versus packed into a bus, train or car, which do you think will afford you the most opportunity to contract an illness?
One other thing, without enough sleep, exercise or not, we are probably asking for illness.
