1. Shave your legs, or don't, I don't care.
2. Don't flip your stem or lower it if it puts you in an uncomfortable position, otherwise, why not?
3. Bikes must be 14.99 or heavier according to UCI regulations. But unless you're Euro pro you might as well ride a bike that weighs less because nobody is going to weigh your bike prior to a cat 5 race.
4. It doesn't take that steep of a hill to hit 40 or 45.
5. Nobody should ride in the rain especially if you have an expensive bike because it is bad for the bike. Only if you have a rain bike.
6. Nobody should stop at stop signs if the coast is completely clear anywhere.
7. Just shave your legs, or don't, I don't really care, nobody cares.
8. Shave your face or don't I don't care.
9. It sounds to me like there are probably some things you should let your LBS handle for you.
10. I don't know what Jesus or prayer has to do with cycling but maybe you should keep your head up and focus on riding so you don't hurt the people you are with and stop thinking about god.
11. Lists are dumb.
