Great annual checkup w/biking influence...
Had a checkup last week for the first time in 2 years. I'm 52 now and started riding again this spring after decades of doing other things instead.
Cholesterol 2 years ago: 208
Cholesterol now: 185
LDL (the bad stuff) 2 years ago: 167
LDL now: 126 (!!!)
Doc asked if I'd been taking the statin drug that she'd prescribed 2 years ago. I told her "no", then she asked "Have you been doing anything active that's new?" I told her that I'd started biking earlier this year and have ridden about 500 miles this summer. (I'm a pansy, I know... :-)
She said "Then that's the only explanation I can give you for the lower numbers. Keep on biking!"
