What bores you?
I do not have enough downtime in my life to get bored over anything. Everything I choose to do brings fulfillment to my life in one way or another. That being said, I do not participate in things that would have the opportunity to bore me. However if I did, these are things that I have no interest in, whatsoever:
Watching golf or tennis. These are participating sports, in my opinion. Watching live is a better option but totally boring unless I’m physically playing them.
That’s about all that I can think of.
