It's wild to think about how short human history is. For example, the iron age started approximately 1200BC, which means that if you are 32 years old you have been alive for 1% of the time humans have used iron. If you are 54 years old then you have lived through 1% of horses being domesticated, the wheel being used for transport, written language and living in towns. 🤯

@gundersen @sgf it’s pretty mindblowing to realize that my grandmother lived from horse and carriage to the nuclear age, the moon landing and used a computer to manage her stocks over a modem in her retirement.

Human history is a blip in the grand scheme of things
