After a certain age absolutely. They're necessary when/if you're defending yourself though. People get paid to fight these days it's literally a profession.
Fist fights should have been dead long ago. They don’t prove anything so you’re better off getting a professional involved to help sort out the issues cause fist fights are stupid.
No .but would prefer mixed martial arts. Some people tho make a fist fight look trashy and probably just need therapy which is why they are sloppy distracted by feelings and ego
