I don't think it's being a hypochondriac if you have actual symptoms that people go see the doctor for. If they could point to a test and go "Look, there's no way you're going to have a heart attack in the next two years, your X level is too low", then I'd be perfectly fine. It doesn't seem like there's a good test for that though.

Funny thing was, for the longest time I always thought "I'm pretty damn healthy, except for the allergies and asthma." Never really worried about my health much, except a little when I got a bad case of bronchitis.

Those thoughts and feelings suddenly stopped right around when I turned 30 and started getting combinations of minor symptoms just about everywhere on my body off and one all the time.

Probably also that's when I started knowing people that died really young and suddenly (or had close calls) from various things like sleep apnea, heart attacks, leg clots, aneurisms, etc. Seriously, video/board game industry has had quite a few of these young but sudden deaths lately, including some people I knew personally.

When you have symptoms that match those things, it's hard not to feel like it's better to be safe than sorry.
