My husband knows his medicines but takes them largely because the doctor says to. He's not into taking responsibility for his own health, thinks doctors know more about him than he does, etc. It is interesting to me to look at how medical practices have changed in the last 45-55 years; in its way, it's kind of like how computers have changed, etc. I had a doctor come to my house in the 1950's, when I had measles; I still remember it and his having my windows covered with heavy blankets, etc. so my eyes would not be affected by the light, and his little black bag, etc. Now, we are going to have Obamacare and things are so much less personal and there's a zillion more medicines than there use to be, etc.
