I work at a university, and as a middle-aged woman I find the young male undergraduates almost always move aside so as not to bump the mom-aged lady. The last time I was slammed was by a small woman who chose to walk down the dead centre of the sidewalk, and I chose not to step off into the snowbank to get out of her way. I moved to one side, she stuck to the middle, and she bumped me pretty hard. Since I was a lot bigger, it wasn't much of an inconvenience.

Back in the 90s there was a rash of young guys flinging themselves through concert crowds upending people, which was just bizarre. I actually hip-checked one such young arsehole and knocked him staggering, and I hope he felt as stupid as he looked.
