Sam,
Consider it ABSOLUTELY necessary unless contraindicated by sensitivity, or ulcer, or any bleeding irregularity.
If you can take it, you SHOULD.
It really will do more to avoid a heart attack or an ischemic stroke than any pill on the market.
I take AT LEAST one generic 325 mg. tab every day, and usually 2 (and very often 4 or more because of aches and pains of dotage.
