It depends on your definition of old, and boring. I don't consider myself old, but I have always been kind of boring. Over all, things are waaaaay more exciting now then in my 20's. So that throws a wrench in the theory.
Since you want 'proof', describe your idea of 'not boring'... seeing as excitement is kind of subjective and everybody is going to have a differant view.
Here is an example. Went for a hike yesterday. I was very excited to look up and see ridable snow in some chutes.. My girl could care less, she was more interested in the garnates captured in the rocks around us. Her highpoint of the day was finding a large pea sized gemin the trail. Mine was a sweet BC parkou 360 stump- water gap- to rock. How do you measure the bore level?
Talking about bills, finaces, and my health problems,, yes, that is the boring reality of being resposible and aging, but not older. no need to focus onit.
Does that even make sense?
