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 I remember reading somewhere that if your arms outstretched represent the duration of life on earth, humanity represents the distance your fingernails grow in a day.
@scudderfish Wow, that is the most far-fetched analogy I ever encountered. 😃 @gundersen
