There’s an old professor who I often see in the statistics department at my university. He’s usually hunched over a bit, walking slowly and shakily with a cane. He’s always dressed in a suit (but no tie). The other people in the department say hi to him as they pass him in the hall, like an old friend. He doesn’t say much; when he does speak, his speech is often a bit broken and hard to understand.
I found out recently that this professor is very well known and respected in the field. He is over 90 years old and still goes to the department all the time. I don’t know if he’s actively doing research, but he’s definitely still active within our department.
He’s done statistics for most of his life, so I guess our department is his home. That’s true dedication to his work. I wonder if I love statistics enough to be that dedicated to it when I’m 90, if I’m lucky enough to make it that far.
