Nothing, actually, but when someone tells or asks me something...usually trivial, I might do a bit of research for them. My sister does that often, and I will get back to her.
But come to think of it - how about the ways you observe nature and notice tiny changes in the ecology from year to year. I've always had the impression that you have a deep love of it.
Well I am sure so many things. But then I have enough on my plate to explore already doubtful I will ever get to them. We cannot explore absolutely everything. Sometimes is better to stick with what we know we can do well with rather than going off into the unknown.
In actuality, the uncomfortable feelings I'm having as I take time taking it easy make me not love it but I know it's good for me and I continue to take time. And I ain't giving it back, ha.
