Tri Challenge: Fitness becomes a family affair

Since January, six iReporters have been training in the Fit Nation Triathlon Challenge. We’re following along as they prepare to compete alongside Dr. Sanjay Gupta in the August 7 Nautica NYC Triathlon.

When this whole process started, I said I wanted to do the Tri Challenge for me, for my patients and for my family. A perfect example of how the decision has led to changes in my life and changes for my family happened on the Fourth of July.

The Fox Firecracker 5K is run in Kaukana, WI every year on July 4th. None of us have ever participated in it even though it has been going on for years. My wife and I decided that the whole family should do it. Amazingly, everyone agreed.

“It’s probably the closest you can get without having the real thing. The smoke, the smells, the noises, the injuries,” Potter says after exiting the simulation.

What the Yuck: Does flying make me sick?

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.
