Better to be over than under.
For example, better to be over caffeinated than under caffeinated. Also from a economic perspective, better for things to be over priced than under priced.
Also, from a weightlifting perspective, better to attempt to lift a weight you consider over your abilities, rather than something under your abilities.
Over powered is better than under powered. Also, with your kid, or life, better to be overly cautious than underly cautious.
This is also the wisdom of wearing a face mask, better to be overly cautious than under.
