I don't know what I weigh at the moment. I was considered "thin" for most of my life, but probably not now. What I don't like is how hard it is to buy jeans now-- it's not so much my weight, but how it's distributed.
But I've mostly switched to cargo pants and that seems to have solved the problem. Fortunately, nobody much cares what geeks wear to work, even in a business school.
I do need to build up my endurance again, though. I used to bike to school, 12 miles each way. I don't think I could manage it now, especially with New England hills. I'm trying to get back into shape this summer, but with the allergies it's been tough.
