If anything it's surprising we're not even fatter and even less well-rested. We live in a friggin' world-class carnival. Describe some medieval monarch living in some kind of environment like that and we'd simply assume they'd be a wrecked, fat drunkard with perpetual bags under their eyes in short order, even if they had the best of intentions and pretty decent character. But we wonder why we're fat and tired and write and read books about it and try not to see the obvious cause, and the cost of fixing the problem.
kitchens are expensive. the historical urban poor often lived in a corner of a room and bought their food from someone who had a kitchen. it makes eating home cooked meals feel absolutely decadent!
(one thing i haven't yet understood: food was cheaper than a penny, but there were no farthings or ha'pnies till much later. indeed, a penny bought about $20 worth. so did they buy meals a week at a time, and get a pastie a day or something?)
For instance, going to the circus was fun, but quickly forgotten. A local stunt pilot flying overhead only gets a quick glance.
A few minutes of a YouTube compilation gives more amazing entertainment moments than my entire childhood.
No wonder we have trouble falling asleep.
