We know our brains don't have an infinite amount of memory. The brain is limited in size and the maximum amount of memory the brain can hold is also limited, and the long-term memory capacity can be say 50 Gigabytes or even many terabytes, but it'd eventually run out.
Can the human brain run out of long-term memory? What happens if memory maxes out, for example, when one photographically incorporates ten thousand movies into his head or memorizes 100,000 books forwards and backwards down to the very last letter? Assume we of coursse have long enough life span or possibly near physical-immortality for the person to test the brain to the limit.
Do immortals have to forget things every few thousand years or so? Do the newest memories overwrite the oldest ones when our brain's say 100 Gigabye drive gets filled up? And we eventually forget our 4-year-old birthday party, the childhood, young adulthood etc etc, or at least forget all the not-so-important-but-we-wish-we-remembered things.
What if we can't upload our brains to computers and dramatically increase our memories, what if those are incapatiable/non-computational. Then we're stuck with our own heads with nowhere else to expand.
What happens if memory runs out? long-term memory maxes out? It's not a problem in a person who only lives to 100, but near-biological-immortality would require about .... infinity in memory capacity.
