I'm 55, had a heart attack last yr.  Was never heavy before, but now am trying to watch weight, and lower cholestrol.  Currently weight 157 and have been trying to lose for a couple months.  Normal weight for me has been about 125-135 for years.  I did quit smoking in this past year which probably contributed to the gain, but now I can't get it off.  I Exercise daily for cardio at least 20 min but usually more.
I love to garden and have recently retired.  I look forward to the spring and getting out doors again.  Right now I go to a local gym.
