Correct my passage Please (Memory)

[EMHM]

I have written this passage just for practice. Please check it for me.

"I still remember names of my class mates in the primary school, but the names of my 12[SUP]th[/SUP] grade mates are not clear in my mind. I wonder why is that? If the storing of thoughts is in sequence, the first In, the first to forget.
I watched many videos about the memory mechanism of storing and retaining the names, faces, smell and even the taste of food. Every time I watch such video, I try to understand it carefully, but still I need more information in this regard.
What type of memory that can keep all that much of information for that long of time with that degree of accuracy?!"

I've watched many videos about the memory's mechanism of storing and retaining [STRIKE]the[/STRIKE] names, faces, smells and even the tastes of various foods. Every time I watch such videos, I take great interest in them, [STRIKE]try to understand it carefully,[/STRIKE] but still I need more information in this regard.
[STRIKE]What type of[/STRIKE] I find it truly fascinating that our memory [STRIKE]that[/STRIKE] can keep [STRIKE]all[/STRIKE] that much [STRIKE]of[/STRIKE] information for [STRIKE]that[/STRIKE] such a long [STRIKE]of[/STRIKE] time with [STRIKE]that[/STRIKE] an incredible degree of accuracy!

Perhaps:

The first in should be the first out

Or:

The first in should be the one I am most likely to forget.

(Emotional content has something to do with memory storage.)
