I don't see how anyone can be bored.
But, my perspective may differ because of two things:
I live in Florida and the weather here is almost always decent. It gets "cold" a few times a year and "hot" in the summer. But even when it is hot, it never hits 100.
Secondly, I shoot. My main hobby is trap, but I also shoot rifles, mostly milsurps. I shoot trap, during the winter, 6 or 7 days a week and, in the summer, 3 days. (Our club shortens its hours when the snowbirds go home).
In the summer, I shoot rifles two days a week, on days the trap club is closed.
I also shoot handguns somewhat irregularly, but do teach CCW classes and shoot during them.
And, somewhere in there, I have to reload for all these guns.
So, being retired means a busy life. Up at 6AM or earlier, bed at 11 or 12 at night. Church Sunday mornings and evenings and again on Wednesday night.
A wife? Family time? Fortunately for me, she still works and then, on the weekends, shoots trap with me.
There's simply no time to be bored.
