I've been keeping a diary for 20 years. What I did every day or various notes have been written in it. I bought something, I replaced the light bulb in the kitchen, I went somewhere, these daily activities are recorded in it. When I can't recall something, this diary is helpful. In other words this diary is a kind of memorandum.
Today, while I ignored the warning of a low battery in my PC, HP200LX, it suddenly froze and the data for about 10 months after the last backup was destroyed. I hopefully thought that it would work a little longer. I was so sorry.
