Reason behind the Heart rate monitor. 

When in Hawaii 6 years go, there was chance to dive with the sea turtles.
Never having dived before, though I'd try it. Went on the course in the hotel
pool and was OK. Lungs felt a bit dry but OK.

When we were out at sea and all 6 of us were hanging on the anchor rope before
going down, I said, not for me and got back in the boat. Borrowed some goggles
and a snorkel and went with the others for an hour or 2.

Last year went the Philippians and decided to dive with the whale sharks.
Packed my goggles and snorkel and off we went. At the resort, I decided to go
diving. As I put my head under the water, I panicked. My hippopotamus or fight
flight brain said, dangerous get out. After some time I managed to get my
cognitive brain to override my subconscious and I did go diving a few days
later. 

So with living a "normal" life my fight flight level had changed. Self
employed and machining for a living has probably taken its toll. One mistake
and start all over a gain. 

The idea behind the monitor is to observe my heart rate during my day and see
if anything increases it. If it does, see what I can do about it. 

Here is some interesting reading. Just one of the may I have found.

The other benefit of the device is to check sleeping patterns. Need to couple
a 3 axis unit into it as well.
