Yo that signature is the exact reason why humans are unique, we each are 100% unique, because of the combined learning and efforts of everyone else. If you think about it we will always be unique due to exposure. You may have been around this person for 40.000003333 hours that year, another person will be around that person 40.2129939 and you have to factor for the hundreds of other interactions and influences and time spent around different acquiantances and that is a completely different impossible ratio for any other humans in history to reach and then you account for everyone elses unique amount of time spent and then you think about all of the different combinations those humans received. No human will ever be exactly the same, we're all unique because of math. I'm high as fukk so idk if it makes complete sense but I started thinking about it and we're all unique at our cores even by a slight degree just because of who we are around.
