What's got you so concerned? I recall the cholesterol thread a few days ago
I can relate to your "worrying". When my coworker nearly died, it set me into being healthier and treating my body better. I've become one of those healthnuts I used to so enjoy mocking!
I have no idea what's kept me worrying about heart health and all that. Perhaps because I'd had some sort of guilt for not taking health more seriously. Its not like I am in any sort of trouble, someone else's issue sparked my own awareness.
So like you, I'm trying to wind down and just live life. Not every pain and body ache is a symptom of bigger trouble, so I need to stop trying to over-analyze things

Too much idle time,to many medical reads, me thinks!
