That sucks. My dad used to run marathons, my mom used to have a BMI of 20 and my brother used to wrestle and row crew. Their all overweight now (brother hit obese). They go out to eat all the time  (too tired to cook) order appetizers on top of the meal because they are fun and nobody exercises any more.  I grew up in a healthy family but I'm the only one left :(  They all claim it's part of getting older.
