A high-five to you too! 😊
Yeah, they are good for you too because not only do they have physical contact but they are generally associated with reward in our brain and triggering endorphin release. If we are talking about western countries, it has culturally become imprinted in our brain to see high-fives as a mechanism of reward-like behavior where a person is satisfied, happy, and/or proud with something that we did so is reaching out for some kind of confirmation/affirmation of that, so kudos for the initiative!!!
