"It is a good thing that the young have no idea about growing older.
It would scare the living shit out of them."

I'm 51 and I can really relate to this. When I was 48 I had a terrifying reaction to my thyroid medication. My heart started racing and booming in my chest and I had the anxiety from hell. I thought I was going to die that day. I sometimes wish I could go back in time to when I didn't know what true terror was all about. It was so traumatizing that I was in therapy not long after this incident. I didn't know at the time that it was actually harmless and all they had to do was lower my dose.
