It's not a bad idea to check it out. Your resting heart rate is an important indicator of health. If it's well above 100 or below 60, that is a good indicator that something is wrong and should seek professional advice. It's one of the simplest things to monitor and with apps you can get on your phone, it's never been easier to get an accurate measurement.
Yeah, I need to start dedicating more importance and time to my health, namely what I eat and the exercise I do, but having two kids really takes away a lot of time.
