Nocturne, what happens if your doc says you need OHS next year...? The arguments you present to this forum are silly I got my valve at 31 and have already made it past 80.....and believe me, I am just a normal old man. That blows the hell outa your theory. BTW, I have lived longer than both my parents, my only sibling, both of my uncles and 3 of 4 of my grandparents so I don't think "it's in your genes"....and BTW my life and lifestyle has always been very normal......and, at times, I pushed the envelope more than a little.
Don't waste your time with a lot of "what ifs" and for Gods sake, lighten up, corrective surgery IS NOT a death sentence unless you choose to let it be. I do believe in "self fulfilling prophesy" and with your attitude you ain't got a chance of making 80.
