Of course, why just yesterday I used violence to solve a fellow's computer problems and then when my car engine light came on I fought 47 men and the light went away. I shudder at the day I suffer heart failure, I can't imagine how many I'll have to fight to magically cure it, on top of the people I have to fight that day to make crops grow dinner.
Wait, was it fighting? No no, I'm pretty sure there might be some other pillars to human society... Mutually beneficial coexistence of specialists with a strong democratic rule of law to settle disputes, or at the very bare minimum some temporary excuse to maintain a social contract of minimization of harm done to each other? No no no, definitely fighting. Fight not hurt brain like think think do.
