It’s always nice to stroll down memory lane. Smoking was good for you, asbestos was a wonder material, big block V8’s were desirable, playing cricket on the street and cars slowed down while you got out of the way. For all the crappy stuff it was a good time to be alive.
One of the downsides was the size of batteries. Fortunately some smart people figured out how to make batteries smaller. Imagine the size of your smartphone if they hadn’t.
