Sag Harbor' brought me a new readership - it's a coming of age tale about growing up in the '80s.

Even growing up the way I did, I was shocked by the level of poverty I saw as a college student. I thought the best way to understand it was to get close to it on the ground level.

I don't think we can fix poverty without fixing housing, and I don't think we can address housing without understanding landlords.

I teach at Harvard, and focusing on understanding this problem on a national level is a big priority of mine right now - where evictions are going up and down, what cities are actually instituting policies that work, what housing insecurity is doing to our cities, neighbourhoods, our kids.

Mental health affects every aspect of your life. It's not just this neat little issue you can put into a box.

If Obama wanted to make radical changes to America's health long-term, all he has to do is treble the price of sugar and salt.

When I inspire myself, I want to spread the word because its important to be healthy. I don't think they're teaching us enough about that. I think we should eat better and exercise. Look who's saying that - a guy who was 300 pounds - but I'm doing a lot better than I used to. I'm letting people know its important because it makes you feel better.

When man possesses a good, sound body that does not overpower him nor disturb the equilibrium in him, he possesses a divine gift. In short, a good constitution facilitates the rule of the soul over the body, but it is not impossible to conquer a bad constitution by training.
