36 is not too old for anything. Even if someone says it is, it doesn't mean you should listen to them.

What if I want to be a MD or pilot?

I think still not too late for an MD or pilot if that is your passion. Just that ROI may be effected because of total working years remaining.

Then you would need to go to medical school or pilot training at age 36, which loads of people do.

That may depend on your juridiction.
