I went thru the stress tests last week. Did walking on the tread mill. Injected with the what ever the hell they use. Walked till I like to have keeled over, Then in to the Cat Scan or whatever the tunnel is called. Flunked that right away. Had to get some meds to calm me down 'cause I have Clostrophobia real bad. So slept thru the whole ordeal. Called the doc yesterday & everything OK for my age. Good news to me as I'll turn 81 this June.
