Resting heart rate of 38 beats per minute

I have been saying for some time that I believe my resting heart rate in the high 30s or low 40s, so this morning when I woke up I decided to measure it.  Luckily my heart rate monitor and chest strap were right next to the bed, so I didn't have to get out of bed in order to get them.

After attaching the chest strap I put the watch in training mode and waited a few seconds for the heart rate to be displayed.  At first it was showing 42, most likely caused by the slight exertion of reaching over to get the watch and chest strap, but after a few seconds it started going down.

For quite a while it hovered around 39, and then a couple of times it went down to 38.  A resting heart beat of 38 beats per minute is pretty damn low, but it is not the only time in my life this has ever happened.  I recall once before having a VO2 max and resting heart rate similar to now.  I was much younger back then though, so it is great to see that so far I have defied the effects of ageing through my training.  Don't tell that to the hair on my head though, which decided to start taking flight a few years ago now.
