Right on, Leah.
With regard to statins, though -- they have many other powerful positive effects, particularly on coronary disease (non-cholesterol) and I think some other stuff, and I believe longevity. So if your doctor has prescribed on for you, take it. I take Lipitor not so much on the basis of cholesterol (although that's why he has me on it -- wants mine below 100, LDL at 70; it is) but for these other reasons. They really are a powerful reason to take them.
One of the questions this article raised for me is -- alcohol and marijuana destroy brain cells. Perhaps that's why they are also depressants? (What about watching TV, then? Does it destroy brain cells?)
The interesting thing is that at least alcohol has the opposite effect on people with central brain damage (learned this from my brother). It's actually a stimulant for them. They sometimes gave it to my brother to perk him up.
Also, did you know that they don't exactly know how alcohol affects the brain and does what it does? (The last I heard.) I was shocked when I heard this -- it just seems like such a given.
