Can a person remember everything?
Imagine being able to recall just about anything. Your mind is like an encyclopaedia or internet search engine with endless names, books, pictures, dates and events.
The first person to be identified with hyperthymesia (超忆症) was Jill Price in 2006. She told the researcher, “Whenever I see a date flash on the television (or anywhere else for that matter), I automatically go back to that day and remember where I was, what I was doing, what day it fell on, and on and on and on and on and on.” Jill considered this uncontrollable and tiring.
However, some people with hyperthymesia take great joy in their extraordinary memory and see it as a gift. Marilu Henner, a TV series actress, knew she had an exceptional memory by the time she was five. She admitted her recall ability helped her remember the lines in the TV series and the happy memories were great comfort for her in her life. Now her trait drives her to advocate more funding for brain research. “What’s more important than creating memories with people, spending time with them, and relating to the world in a certain way that’s uniquely yours?” she said.
Think: If you were a person with hyperthymesia, would you look for the cure? Why or why not?

答案
If I had hyperthymesia, I would look for a cure. It seems exhausting like Jill Price, who found it uncontrollable and tiring. Constantly remembering every detail might make it hard to focus on the present or enjoy new experiences. If I had hyperthymesia, I wouldn't seek a cure. Like Marilu Henner, I'd see it as a gift. It could help me remember important things easily and provide comfort from happy memories. Plus, it might give me a unique way to connect with the world.
