......as part of that job I had to get a physical every 6 months.
which included an ECG, the last of which after 50 years - I maintained a licence into retirement - picked up the need for a couple of arterial stents, so .... if all those ECG's were essential, why don't I need them now ? Realised that I hadn't had an ECG for 7 years so got my local Dr. to give me one anyway. Seems alright.
I do wonder how many drivers hurtling towards me at a closing speed of 200 kph have ever even seen a doctor ?
