I am fortunate enough to be able to say that there is a lot of crossover between my professional and recreational occupations. I am a bit of a fanatical hobbyist, and have too many to find time for let alone list, but here's a sample: cycling, extreme mountain biking, downhill and x-country skiing, speed skating, reading, creative writing, drawing, digital and darkroom photography, filmmaking, gardening (alimentary and entheogenic!), mycology, the study of psychedelics, consciousness and philosophy, and, of course, alkoloidal extraction!
I, for one, cast my vote for the 36 hour day - about the only way i will be able to partake in any of my hobbies, raise a family and not sink my ailing career!
