I always have fear of having a stroke, what should i do?

At risk?: The majority of strokes occur in people with risk factors: high blood pressure (that's the biggest one), carotid arteriosclerosis (don't smoke, check your cholesterol), and atrial fibrillation (a heart rhythm problem - the risk is mainly for people with diabetes or are >age 65, especially >75). You're only 32. Did anyone in your family have a stroke? Young? Did they have risk factors you don't?

Stroke: At the age of 32 and with no significant medical conditions the risk of stroke is extremely low. If you have medical conditions that could lead to stroke then seek medical treatment. If it is a "fear" of a stroke only then would recommend psychological counseling to help here.

Check risks: Read up on risks, then check risks (no nicotine, check blood pressure, keep yourself hydrated), have your doc get a lipid profile, carotid ultrasound, start the "mediterranean diet". Any strokes in family, get workup for "hypercoagulable state". Then, take an Aspirin a day and relax, you did everything you can do (uncontrollable risks such as ethnicity and age are just that - uncontrollable).
