Smartphone is not one of the worse options. It's one of the best options. Thanks to it I'm just discusing ideas with you while lying in a garden. Which is at the moment my preferred way of wasting my time.
No other tool would allow me to waste my time this way. If I couldn't do it I'd read fantasy book I got for my recent birthday but it wouldn't be nearly as intelectually stimulating.
Sounds like a waste of a perfectly good garden. Try looking at a plant for 5 straight minutes. It is amazing the number of details and features and events you can see if you just sit still for 5 mins and look.
I already looked at plants over my four decades of life and they are not that interesting unless you need them for something. And you rarely do.
Besides, I was looking today at small aphid infested tree for few minutes. Even poked some. Then I got bored and went back to discussing you. There are so many minutes to kill in a given day.
