I am an old guy - been riding road bike for distance (all the way across the US once) since I was 12, which was in the 1950s. I know a lot of stuff, including about prostatitis which has currently "grounded' me.
I am also a professor of Biology - cell and molecular biology - and know a lot about muscle physiology. I welcome inquiries. I live in central Texas and work at Texas State University-San Marcos.
