don't let the what if's rule your life.
Exactly. There's being prepared and there's being paranoid. I'm 56 now but at 45 had a near fatal bout of congestive heart failure. Doc restricted the altitude I could go to for fear of HAPE (High Altitude Pulmonary Edema) to a max of 3500 feet. Then 5000. Then 7500 not all that long ago. What I never told him is I didn't completely listen to him. Wasn't crazy-stupid but pushed myself a bit. My husband, son and I had a discussion and we decided as a family that worst case scenario I'd go home in a box. It would suck for them but I wouldn't have a clue. I'd rather be in that box than sitting quietly on the couch, wishing. Again, it's prepared vs. paranoid. Go enjoy yourself.
