I used to get strep throat every year. Only once was it mentioned I *might* need to lose the tonsils. I mentioned to my kids' pediatrician that I got strep every year, and he said once you hit 35-40 strep is rare, and almost never seen in seniors. I asked "why?" and he said "I dunno, I'm a pediatrician."
Well, I am now 43 and have not had strep for at least six years. I vote to keep 'em.
