Imagine being able to remember every single day of your life, all the way back to when you were a newborn.
Australian woman Rebecca Sharrock is one of only 60 people in the world with a highly superior autobiographical memory (HSAM), also known as hyperthymesia.
I think it’s more about preserving sanity and keeping survival resources available. You don’t think about last year’s fight with your neighbor so you can focus on potential dangers in the moment. I believe the storage capacity of the human brain is theoretically unlimited in the timespan of a human life.
Interesting. But still, memories from your whole life would probably take up 100x-1000x what you currently remember, does your brain really have that much free capacity? Although I imagine the mechanism of only paying attention to the memories that are relevant could work even then
