For years, doctors advised people over fifty or sixty to take a baby aspirin (around 80 mg) every day as a preventative, to thin the blood, thus reducing the risk of a blood clot or ischemic stroke. The problem with this is that if you have a hemorrhagic stroke, the thin blood won’t clot and the damage from internal bleeding will be more severe. It’s one of those weird situations in medicine where you effectively have to choose how you want to die or be otherwise damaged: Would I rather have the damage from a clot or from a rupture?
