It depends -- are you habitually around very high-risk people? (i.e. very young, very old, pregnant and immune suppressed individuals) For most healthy adults, the flu is really horrible but it's not life-threatening. In the high-risk groups, it can be deadly. Personally, I never got the flu shot myself until I started having kids -- now I have a 5-year-old and a 10-month-old in the house, with a newborn coming in May, so I get my shot. If you're regularly around hospitals, nursing homes, or clinics where you will be exposed to high-risk people, then it's a matter of social responsibility to not be passing the virus around to people who could die from it. If this is not the case for you, then it's really your own choice of whether or not to get the shot.
