Good luck man,
It seems that it comes with aging....medical scares. I made 52 yrs or so with nothing at all and then in the last few yrs I've had several. For a few days it seems like its all coming down, and then (usuallly) it turns into something you can handle just fine. Then there will be another scare down the line. In 10 yrs you will definitely look back and think about how young you were at 49.
