So this is kind of interesting (and very speculative).
I randomly wondered to myself, I wonder why obesity seems to be a more recent (relatively speaking) thing. And then I thought about where the majority of people spend their time these days.
The same year American obesity started to trend upwards substantially, Apple Computer was formed:
Since Apple at that time was one of the driving forces (if not the driving force) behind the personal computer, I wonder if there is a correlation between personal computer ownership and this upward obesity trend.
Isn’t speculation fun?
