My son was born with a heart murmur, but my daughter inherited her heart problem from her birth mother, who died at the age of 33. My daughter is 43, and has outlived her mother, which seems to be no consolation at all. I suspect her years of using speed have more to do with it than anything congenital.
My son’s murmur disappeared by the time he was 17, so he was able to enlist in the army. He tried to OD while smoking coke on my 45th birthday, and it was enough to scare him straight. Now he has a mass in his left breast.
Me? My mother and father both had heart problems, and I had a murmur when I was a teen. It progressed, as I aged, to a circulation problem, which means I have had to carry a vial of Nitroglycerin with me for at least 40 years.
Is that like the trick of putting books on your head to practice correct posture? I can see that it would tend to make a person move with carefulness, if not grace.
