I had a college professor that teaching was his fourth career, he was in his 90s. He started the first class of each term with “I’m not going to remember any of your names. I’m old. My brain can only hold so much. If I put your names in my brain, something else will fall out. It might be my wife’s birthday, it might be that I need to take about a hundred pills a day. Either of those, and I’m dead by next week.”

Simply have scheduling conflicts so you’ll forget even how to roll a die

Is it me or once again, DnD is the issue instead of the people?

This is why I play rule light, I can’t remember my player’s name, so a complicated rule heavy game like D&D? Nope
