I like to talk to people on the phone. I don't like to do critical stuff by text message.

I found ways to maintain my performance through working with professionals and doing things that other people weren't doing. Later in my career, I had a great physical therapist who kept me out on the track. We were doing innovative things like ice baths back in the early '80s when everyone else thought it was crazy.
