I just saw your cholesterol and fish oil comment. I finally got around to actually adding Omega 3 supplements to my regime and realized, a week later, that I felt better in some hard-to-identify-way. I'd given a few bottles to a male friend. He said that he also feels physically better since taking them. Our respective diets had few omega 3 sources other than almonds so that was an oversight on my part. I'll be curious to see upcoming cardio-profile blood work results .
