15 years ago I was me.
I am still me today.
But that me of 15 years ago and I do not have a single cell in our bodies in common. Every single one has been replaced. That's weird when you think about it.
It gets really weird when you research it:
Quote:Recent evidence indicates that DNA methylation may serve as a contributing mechanism in memory formation and storage. These emerging findings suggest a role for an epigenetic mechanism in learning and long-term memory maintenance and raise apparent conundrums and questions. For example, it is unclear how DNA methylation might be reversed during the formation of a memory, how changes in DNA methylation alter neuronal function to promote memory formation, and how DNA methylation patterns differ between neuronal structures to enable both consolidation and storage of memories.
