This guy is no troll. He has been around awhile and posted over 500 posts. Here may be an insight from his "about me" page:
Biography Currently transitioning from DF to a trike due to 4th of July accident. Muscles I didn't know I had are plaguing me as are lingering respiratory issues from bronchitis/allergies. I never was fast but I used to be able to pedal all day. Rehab sucks. Recovery from "concussion" is no fun either - lost sense of balance, sense of timing (cadence-related), and have becom every light-sensitive (thank God for sunglasses).
Seems to me has has been through a lot, and it has taken a toll, along with the "dad" situation.
