One of my kids put his ear to my chest to hear my heartbeat, and claimed he couldn’t hear it. The other kid tried, and said “I hear it, but it’s so slow!”
My resting heartbeat averages 54 beats a minute, according to my watch. I’m proud of this only because I think it makes a case for all the exercise paying off.
Hopefully it helps to keep me alive longer so these little sweeties can keep putting their ears against my chest.
