If you want to get jab, exercise at your own risk.
As I have said, many people wouldn't have died suddenly if they didn't exercised. The risk of death gets higher if you had already passed the age fit for exercises.
It doesn't mean you look good outside means inside also will be good.
Just walk around and let the blood flow is better than inducing shock to it and receiving death as a result.
Dey, the inside and the outside are totally 2 unrelated subjects.
