I'm 43, and aside from a dermatologist I only see my gynecologist. He checks everything though, even orders complete blood work (which I'm way past due for!). I asked him if I should see an internist for a complete physical and he responded "not unless you want to be poked and prodded and have a lot of unnecessary tests done so they can look for things that aren't wrong with you." Such a comedienne. Anyway, I am going to see an internist when I'm 45 just to have my heart checked and such. Then comes the dreaded colonoscopy at 50! I'm a nurse, BTW, so I have a pretty good idea of what may be ailing me! Knock wood! I feel pretty good now.
