That is so true. We lived in a house that is about 100 years old. Even though it has been updated here and there and is gorgeous, it doesn’t have the electrical capacity of a newer house, and the plumbing - you couldn’t put anything down the drain pipes, they clogged so easily. Structurally it is very sound, but one day when I was down in the unfinished basement, I wondered how much longer it can stand in California. It looked to me like it was poised on sticks. Maybe it will stand firm for another 100 years, maybe not.
Few houses built today will be as long lived as yours I’d bet.
