Somebody actually walked into the bar before. Lucky for me it was really light and just a warmup set, about 60kg I believe. Still took all my strength to regain balance though and my left thumb was so sore the day after because most of the weight hanged on it. I had wrist issue on that hand for a few months due to that incident. If that bar were to fall on my chest that day, at best my ribs would have cracked, at worst I would have died. Man did that guy get a scolding from me, I haven't seen him in the gym ever since then. A lot of these people act like little children in the gym, never aware of their surroundings. They think the gym is a playground where they play with the barbell.
