Two experiences from working in a large office building:
In 1989, I lost 50 pounds in six months. I went from 189 to 136. I cut out junk food (most of my diet) and beer and started exercising. (I eventually put it all back plus more.) Many people thought I was sick but were afraid to ask directly. They would say things like “I was talking to (another person) and they thought you looked sick.” I felt fine but I certainly looked too skinny. I could wear 30-inch waist pants.
Women made up most of the staff in my building. I never thought that anyone was looking at my butt but I had two women tell me that I had lost too much weight in the buns. I had an answer by the second time. I said “If you liked them, you should have said something when I had them. Don’t tell me now when they’re gone.”
I had a beard until 1999. I have had a mustache continuously since I went to Pitt in 1971. (When you’re young, you want to look older. When you’re old, you want to look younger. ) After I had the beard cut off, four people ask me when I started growing a mustache.
