[MENTION=137127]Papa Tom[/MENTION], I'm not convinced that's what was going on with me at age 20. I remember huffing and puffing and not going fast. I will never know. My breathing rate barely goes up on that hill nowadays. I'm talking about the hill that the George Washington Bridge is on in Manhattan. I lived north of the hill (at the bottom) and work and college were south of it, so I climbed the northern slope in the morning and the southern slope in the evening.

Later in life, I lived in a hilly part of NJ and learned to pace myself. I'm not amazingly fast, but I manage to climb most hills without stopping or walking.
