He!, tis difficult, yes. I thought I had the health thing licked by cycling 90miles or so a week to work and back. Thin, fit, and could eat what I liked. Then I bought a motorbike. Now it's a case of motorcycling till I can't fit into my leathers anymore, then getting back on the pushbike until I can, but every time I have to build up my fitness again it's harder and more gruelling, but I just don't have the willpower to cycle say 3 days a week, or do some extra training at weekends to counteract my internal-combustion induced lardiness. In terms of my waistline at least, I'll be glad when the oil runs out!
