Ouch! Don't Trust a Rusty Chain

I picked up a Diamondback Sorrento that I found on Craigslist for my oldest son to use as a commuter bike.
It looked good, except there was some rust on the chain and cluster.

It cleaned up nicely, and I took it for a spin up and down the street in front of my house. Everything checked out on the first pass, so I sped up and shifted up. As I stood up, the chain broke, and I ended up sliding to a stop on my face. No serious injuries, but I had to get my nose stitched up in the emergency room.

In 40 years of cycling this is the first time I have seen a chain link break.

What he said.

For the record/posterity ... for my $$ ... tubes, tires, chains, cables, brake pads and housings are set to [default = replace!] ... unless they can prove I shouldn't

I just can't picture how snapping a chain could lead to sliding on one's face.
Then I read again and realized you were pedaling standing up.

I only used to stand up when I was still beggining, then I learned how to use my shifters and have never had the need.
I guess this is another reason to avoid standing up.

This is why I ride with my seat low. Other than it is harder to absorb the impact by bending your knees, it also makes it harder to put your weight farther back. Albeit, you can put your weight around the back tire with a high seat, if you have a low seat you can literally straighten your arms and go much farther back.

I had my first experience with chain failure recently. Got a '75 Peugeot off cl, sort of cleaned/tuned it and went for a ride. It broke on its maiden voyage. I put it back together and it broke on its 2nd ride. It's one of the only chains I decided to toss.

I've broke about 4 over a mildly longer period of time. The last resulted in a broken collar bone. The one before that also resulted in a sub 5 mph crash with no injury.
