All Mortal Affairs Fade Into Oblivion

Summary

My husband has hyperthymesia. He possesses a highly superior autobiographical memory. He can recall the exact weather of a random Tuesday twenty years ago, but he has forgotten my birthday for five consecutive years.

Whenever I brought it up, he would give me a blank look.

"Is it coming up? Next week?"

My birthday was last week.

I used to joke with my best friend Sasha that even a genius brain had its glitches.

Until the day I was cleaning his study. I found a folder on his desktop named "Health Tracker."
