I disagree. I box for sport, and I prefer to listen to my own music when hitting the heavy bag. Wraparound bluetooth headphones are the way to go because I can leave my device in my duffel bag several feet away.
Really have to qualify your comment. All horrible people will eventually become elderly. Despite the "wisdom" that such people may have, many have an incredible ability to wreak havoc in the lives of others... to the point of being a net negative on future generations.
You bring up a good point. There's no qualification test for wisdom. Is someone a bitter dogmatic psycho? Or are they warm and truly emotionally intelligent? No way to know. One problem is that there is no real regard for wisdom in modern American society. We value youth and energy over wisdom and depth. So, why even be bothered to think about such things?
