I remember details from every day of my life from the past 10 years

Why I don't remember from before that? For what reason it only started 10 years ago? I'm 25 now. Anyone else have a similar thing?

I'm asking here because when I brought it up to a few people in my real life they said they don't remember like me so I guessed they're just brainlets and I'd ask here and maybe find familiar people
