Before starting a cardio-respiratory exercise program, which medical tests might you considered receiving from your doctor? (no options, written answer)

Explanation:

I'm 80.

I want my doctor to tell me I'm not over exerting myself by doing anything beyond walking 4 blocks to get the mail.

I want him to order blood tests (I live in Canada. Those come under public health care). I want him to tell me if my potassium and sodium levers are normal, to say nothing of red and white cell counts. And platelets. I don't want to get a cut and not be able to control the bleeding.

I want him to assure me I'm not diabetic. You should be able to guess what test will determine that.

I want him to take my blood pressure and assess it for me. Is it too high, is it too low? What is it? Do I need medication or am I safe without it.

I want him to take my temperature. I want to be assured I'm not running some sort of fever. At my age, fevers and not jokes, and they have a 0 rating for a sense of humor.

I want him to test my memory capabilities. I want to remember what my limit is for exercise and not over do it.

I want him to test my reflexes. I used to be able to juggle. I wonder if I still can. Am I fast enough? Am I sensitive enough?

Hearing? How bad is my hearing loss? It seems severe to me. The neighbors routinely tell me they missed the 3rd news item. Could I tell them what it was.

Well those are for starters. My family doctor would do all of the above things without being prompted.  

the last statement is correct i.e.

when your heart is not pumping enough blood around your body because your heart is severely failing, you may need an artificial heart. an artificial heart is a mechanical device, about the size of an orange, that is connected to your heart or implanted in your chest to or replace a failing heart.
