Make A Sentence Double Trouble 40: Safety... or not

You're right - people? did ridiculously dangerous jobs 100 years ago. Although today we have a better understanding of exercise so people can lift weights and do cycling to become stronger

I wish there were a time machine which could make my ten years younger? Bye the way? a lot of workers did dangerous jobs without ? protection in the past? people have become more and more weak?

good idea, short video, great? teacher I like your videos teacher :)
