I don't know about the walrus thing and I think everyone has a different metabolic rate. Some people require less and can be O.K. with what they are used to. At home I eat like a horse and it all goes to my gut. I think I'll deliver soon but not sure what it will be. <img src="/forums/images/graemlins/grin.gif" alt="" />OTOH when I'm in the woods, I eat way less that at home. I know when I used to bike ride, (several years ago) I could sprint uphill as fast as anyone but it was hard to sustain a cadence andkeep up with the stronger riders. I guess I'm kinda like a rocket and others are like a train. I'm working on slowing down and smelling the flowers. I guess that's the reason my son bonked 3 times while we were climbing about 1,100 ft in about a mile on our last trip. Maybe next time I should try to follow not lead.
