Last dose of Aspirin Prevents heart attack or Strokes

There is a article on Phillynews.com about a low dose of aspirin that could prevent the first heart attack of the first stroke. It also say "anyone currently taking low doses of aspirin to reduce risk of first heart attack or stroke should talk to their doctor before they stop." I honestly think that if aspirin can reduce the risk of having a stroke or heart attack then it would be a good idea. Therefore I think that you should talk to your doctor before taking the aspirin. If you don't talk to your doctor about the aspirin you take then it will mostly cause your body to cause a reaction to your synisis or set off a certain nerve in your body and that will send you to the hospital on a 50-50 percent chance. Also if you know what aspirin your taking then you already know what your doing.
