Honestly, how much do you think your memory can hold? A textbook shows that a typical person's memory can hold as much info as 500 complete sets of Encyclopedia Britannica. Personally, I've always taken the ability of memories for granted. However, I was totally mistaken. There are real-life examples of people that show the greatness of our memories. Here is a woman who remembers every second of her life

I remember how I came out from my mother's womb: Remembering the event of birth would be completely flabbergasting, but in real life, our memory cannot recall as far as that. This is called 'Infantile Amnesia' which is due to underdeveloped Hippocampus in our brains during infancy. It's amazing how memories are actually stored in a physical part of our brains.
Similarly, emotional components, especially fear, are stored in Amygdala of our brains. So if these parts are damaged, we literally lose our memories which sometimes may come handy when we want to start from scratch. Furthermore, evidence from the textbook shows that propranolol can inhibit adrenaline and prevent individuals from remembering painful or emotionally arousing memories. I'll ask you a question at this point. Would you erase your memories if you had the choice to?
"We are memories." Whether we like it or not, memories will not completely disappear, but only fade away.
