Actually it does require a shock, if the heart has stopped during a heart attack. An attack can disrupt its nerve impulse rhythm, which can lead to atrial fibrillation and subsequent heart failure. A hard shock can sometimes reset the atrial-ventricle nerve impulse synchronization and restore enough of the heart function to survive long enough until emergency care is given. In a hospital, I have actually had atrial fibrillation, and they had to use a controlled shock to reset my heart’s rhythm. It’s called a cardioversion.
In our 25 yd lap pool, 36 back-and-forth laps is 1800 yards, just over a mile (1760 yards). That would be 70.4 “lengths” so he must be running a 25-meter pool, which would be 63 lengths. Good eye @jsimpsol.
As for Beacon, I recall a friend having a Golden Retriever called “Nugget”?
