Had mine at 53, did not know until I gained 26lbs of water 5 months later. I now have congestive heart failure, diabetes and heart disease. I am on lots of meds, no salt or sugar diet, and am the proud owner of an ICD. My own personal pacemaker and defibulater. See the Dr. once a year now, all my problems are mostly hereditary, though I would have taken better care of myself, diet and excersise just didn't think it could happen to me. Now I caution my children and they are for the most part listening.
