ack Campin,here is some advice,you have a heart condition?
take some GENTLE exercise on an exercise bike.
It would do you more good than spending too long in a sedentary position at the computer.

I've asked the staff about that sort of thing several times to make sure I got a consensus answer, as I thought the same way as you. The answer was "not on your nelly" - I'm waiting to have an angioplasty in two weeks, meanwhile I should be doing nothing that needs any sort of effort.

There aren't any songs I can think of that address the experience of sitting around waiting for something drastic to happen.
