If they're over 30. isolate.
Most of them just wanna go home, spend time with family, kids, bbq, etc. And go to work mainly for paychecks. They have little fire and desire left in them, so now they just want to work happily, have good job security, grow old and die. And ready to invoke high school drama in a heartbeat to protect this.
I have little in common with these (usually fat) people.
