Just a little caveat here: The pneumonia shots may be "lifetime" but they're not bullet proof! I've had them and still managed to get pneumonia after some queer little throat bug (to which I obviously had NO immunity) last month. I'm 68, but I'm fairly healthy, active, eat right, exercise, stay out of crowds, supplement my immune system... and still got the damn stuff. Luckily, the doc spotted it early and some clindamycin seems to have cleared it up. But still, exercise caution!
