I’m sorry to be negative but I feel there is an element of being “age-grumpy”. Oh things were so much better in the past. Sure some things change our habits, like the phones that you mention. It’s ok. People still enjoy the outdoors. And it’s past it was always music SANs headphones. I run a a lot - it’s crazy how many people run and hike these days, it’s something to be celebrated, selfies or not
