After my Dad passed, I hardly ate for about 4 days. My first real meal was also a pizza, though with slightly less cheese.

It's all a matter of relative size, hence the interest in working out and manscaping.

I think the accomplishment is not the actual reading. I think the accomplishment is the foregoing of all the myriad distractions that are competing for your leisure hours. I became a voracious reader in my teens. I'd read on public transit, while waiting for appointments and in lines, before bed, on rainy days and while waiting for the few good shows 3 channels offered and during the commercials. Later on, I'd also read during breaks and meals at work. I read a lot and it was an easy choice.
Flash forward a few decades and VHS/DVDs, electronic gaming, channel shifting, HBO and its ilk, the Internet, PVRs, online gaming, smart phones, streaming and all the social media flavours, are all brand new competitors for your finite leisure time. I still read a lot but it's mostly short articles and posts. Now my books are mostly read in short increments while waiting to pick my wife up at the subway. So hats off to those of you can manage your time better than me.
