Is the phrase "the harder the erection, the healthier the man" true?

Sexual health

I've read somewhere that an erection can be a measure of a man's overall health? Is that true? Like say if a man gets at least frequent and short lasting erections throughout the day, he is considered healthy?

If this happen it is normal. Men can get erection all day every day. This is true to a point
