Listen, as a person who has been exercising for a long time.

It's going to be packed this month. Every year during January, people sign up and overcrowd the gym as part of their new year resolution. Majority will stop going before February and everything will go back to normal.

It is what it is.

I'm sorry to the people down-voting this person, but they are correct!

You are not the police! So unless you are armed yourself, or have some martial art/boxing experience you should not get involved. If you see someone getting rowdy/crazy at a place, walk away and call the authorities!

You do not what mental issues that person has, you do not know if that person is armed, if that person has fighting experience. You trying to "help" can cost you your life and the original persons' life.
