Don't climb a tree again @lightsplasher because we are too old for that thing and it is fatal to fall from a tree too for an old person. But maybe you can put something on it so it can get hooked up by something like a drone or a long stick.

I remember when I climbed up the roof and couldn't figure out how I can get down contemplating calling a rescue. At that time I can still walk and climb up a bit, it was indeed scary.
