i think you could be on the right track. people with heart disease use aspirin because it thins down the blood, and in your case thinning the blood may offset the increase in blood viscocity due to the increase in rbcs. you have to be careful though, as aspirin is an acid and it causes the stomach to bleed which can lead to ulcers. if you do take an aspirin every day i would say use a small dose and take it with food to reduce bleeding.
