To do either thing well, you have to redefine the rules of normal and understand the mechanics of the machine. Ballast, gas, thermals, hand controls all become as important as perception and each decision is the make or break point of the trip. Normal, for some of us, is a time and a place in the past. Normal is pills, for me three times a day. Normal is sex with responsible planning.
Love is protection and foreplay is discussion.
Up is down, and vacations are a form of work for some of us.
