The thing about trees is they grow old so gracefully. Their bark, with it's deepening folds and scars, tells a story of winter storms, dry spells, encounters with other life forms, and unfathomable patience. As it ages the tree grows ever larger. To stand beneath the awesome presence of an ancient behemoth is humbling and thrilling. What if we humans grew larger (by that I mean taller) as we aged? My 92 year old grandmother would be 15 feet tall. Sure there'd be healthcare issues and building code changes but I can imagine some positive paradigm shifts if old people were giants.
