I brought it up because I get the impression that most folks here are fairly mature or experienced (as I like to call it).   I abhor exercise but am very much aware of the fact that I've already outlived my father by 25 years (and I'm not even 60 yet) and have been a health nut and exercise freak for years.  I include exercise into my day so that it doesn't feel like I'm "exercising" by doing the following,

-Bike to work year round (love them studded tires)

-Work office is on fourth floor and we have no elevator.  I go downstairs every hour  or so to pee or get a drink or have a quick peek at the achingly beautiful (and  single!) project engineer as I pass her office.

-At home I take five minutes each hour to do a few push-ups or play with some 10  kilo dumbells.  I also do a quick power walk down to the corner and tease the  doberman that's tied up at the house there. (Effing thing got loose last year, bit my  thigh and I got to sue the irresponsible owner for twelve grand.)

-In the winter I shovel the damn snow for five minutes every hour.

-have a lot of sex...oops, sorry, that was my inside wishful thinking voice talking.
