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've heard of this very rare ability. The last person I saw on TV that had it years ago when Discovery was still good suffered pretty bad depression. Imagine remembering every bag thing that ever happened to you with perfect clarity, whether you wanted to or not, at the slightest reminder. Every bullying, every breakup, every fight, every injury, embarrassing moment, bad day, car accusing - all of it - as if it had literally just happened to you. My depression is bad enough; if I had this condition I'd almost certainly have ended it all.

Does the brain even have the capacity to remember everything since your birth? I expected forgetting to be a space saving mechanism

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

Your brain seems to actively forget almost everything before age ~4 and most things before age ~7. The phenomenon is known as childhood or infantile amnesia. It’s possible to retain memories from those ages just very unlikely. I think trauma and strong emotions make them more likely to be retained.

There are several theories why but we don’t really know. It’s possible these people have that shut off.
