Do-it-yourself bypass

Helping your heart grow new blood vessels is a natural way to bypass cholesterol-clogged coronary arteries.

Picture this: You are driving down a city highway when traffic grinds to a halt. You can see a miles-long backup behind a distant construction crew that has closed off the two right lanes. Knowing the area, you merge over to a nearby exit, then follow a detour onto streets that run almost parallel to the highway. Once beyond the bottleneck, you re-enter the highway.
