I have returned to the States after a few years abroad and I feel like a freshman in college - I immediately put on 15 pounds. I also have a bad knee that prevents me from participating in any of the activities that kept me healthy in my 20s: tennis, soccer, basketball, softball, biking, hiking, racquetball... One of my goals in the next 12 months is to get surgury to (hopefully) fix that. I would love to meet some like-minded Wellspherians.
