Back in 2015 I had a widow-maker heart attack. That near-death event focused attention on my heart health, particularly when I push to physical extremes during mountain backpacking.
During backpack trips from 2015-2018, heart health beats per minute (BPM) was monitored by pulse feel and count. This year’s challenge was a 40-mile backpack in Yosemite with permit to summit Half Dome’s cable route. My heart health was monitored with an Apple 4 watch. BPM and other useful data on my wrist were readily seen with a glance. (See photo)
