Look at howard hughes he became a crazy recluse for much less.
I also think some peoeple take the "timelines" as presented too literally. I've watched TDK countless times and there is no firm amount of time given from the time it starts and when begins ended. The same goes for TDKR where it isn't stated in stone anywhere that he spent literally all 8 years locked up in his house.
