Because of the prior stroke my risk according to this is high in the next 10 years.  Nothing that I changed in any of the answers would change that risk.

Even changing the age down to 20 did not change the risk.
If I remove the previous stroke I am low risk. I don't trust this latest one, it doesn't have enough discriminatory power, but then according to all predictors I should have been at low risk when I did have my massive stroke.
