Getting your flu shot should give your immune system plenty workout.

It's like sparring at 1/2 power with full pads vs. getting into a full on street fight. Sure, the street fight will give you a slightly more real practice session, but at what cost? There is a lot of collateral damage there.

Yeah, the two times I've gotten a flu shot, it's followed by a few days of congestion and a cough, maybe a slight fever. But it's much better than the time I was down with a fever, lethargy, and light headedness during finals week one year.
