TED (Technology Entertainment and Design) is a global set of conferences curated by the American private non-profit Sapling Foundation, formed to disseminate “ideas worth spreading”.

Since I started working out with Captain Quinn six weeks ago, I’ve noticed some real changes in my body. There’s less fat, more muscle, and a significant increase in endurance. This Saturday, I hopped on my bike and raced out to Coney Island, about 11 miles, and, after a lovely conversation on the boardwalk with a Ukrainian grandfather who wanted to teach me Russian, I raced back. I thought I’d feel fatigued when I got home and sore the next day, but neither was the case. I gotta say, I feel kind of proud (and grateful to my über-cool instructor and classmates).

Now that regular exercise has become part of my norm, I’ve decided to take another step and look into my nutrition. I remember someone telling me that they were tracking their calories via a tool they found on Lance Armstrong’s LIVESTRONG.COM site, and on Saturday, after my ride, I checked it out.

In just about an hour from now I’ll be kicking back on the deck of my friend’s Brooklyn apartment and celebrating the Fourth of July. We’ll do it in the quintessential American style–by having a barbecue, drinking beers, eating apple pie, and watching fireworks. But while I’m enjoying the smoky flavor of my steak this afternoon, thanks to a few articles I had the misfortune of stumbling upon a few days ago, I’ll be wondering if what I’m eating is going to kill me.
