Personally, I would call the original poster "Down hill SMARTY pants" instead of "down hill scardy pants".
I was terrified of downhills when i started biking- very very cautious.
But glad I was! Now I have much more skill and confidence.
I can't believe some of the dinky hills I used to brake on and be terrified of. But HEY, I was SAFE and I slowly gained confidence without ever being reckless or taking chances. Lets not confuse common sense with being 'chicken'.
