Well, I'm with a lot of others -- I wouldn't stop riding for ANYTHING! Threaten my children with immediate and painful death unless I stop, and I'll stop. But nothing else -- not even my own death! If I couldn't ride, why live?
If available, I'd take the pill, though -- for those hours when I can't ride, and for the wintertime when all I can do is short rides to/from work.
International doping commission? I'm not a racer, so I'll whiz on your pant leg -- test THAT!
