@edgarblythe,
There comes a time when balance can be an issue. Mine isn't horrible, exactly, but I'm much more wary than I was a year ago. I hold onto columns or walls more. I use an old stick to go to the neighborhood mail box, which to me is surrounded by hazzard in its immediate area. I highly doubt the city will fix the fked up paving. The stick is from from when my neighbor finally trimmed her mulberry tree (heh, illegal here) and stuff landed on my roof, later with Michael, friend of Diane and I and Roger, clearing the roof. Nice mulberry sticks. Re the mailbox nest, I think I'm paying for earlier design sins.
I don't need the stick otherwise, but still am careful. I'm more wary of people speeding around at the grocery store.
They should be wary of me and others for not seeing them. Not to bore all who know me, but I've quite diminished peripheral vision, and as I'm now more flibberty, I think of them as comets. Or dolts, the ones striding with the smartphones.
I used to design and specify handicapped ramps. Now I have to gird my loins re their sharp angles. Not that I remember ever specifying that angle stuff, specs may have changed. I don't know if all that sharp angle situation is nationally routine.
Even as my bestest remodelling and designing self, I was roof avoidant personally. I could specify them though.
