I found this here:
Does running really lead to achieving new highs between the sheets?? Here's why runners and sexual prowess go hand-in-hand:
1. They’re trained to go for hours; 30 or 40 minutes is nothing.
2. They always have plenty of Bodyglide.
3. Even if you look like crap, they’ll shout, “Looking good! You’re almost there!”
4. When you’re done getting busy, they can work those knots out of your quads.
5. Even when they hit the wall, they’ll keep pushing till they finish.
What do you think? any more for the list??
