One good thing about getting older is that you have a much greater tolerance

1. Yes as I get older boredom is not as irritating

First because time goes by faster the boredom doesn't last as long.

Then also I know it will end. As a kid I sometimes thought the boredom would go on forever.

I've also learned how to entertain myself. If I'm stuck listening to a boring lecture, I can think about other more interesting ideas and keep boredom at bay. As a child, I had not developed that skill.
