The coffee machine thing made me think too. People seem to drink a whole lot less of everything except water. I remember hearing my grandparents talk about making pots of coffee at home and drinking upwards of 10 cups of the stuff during the day. Why has that changed? Were we so oblivious then or are we too conscious now? And Three-Martini-Lunches? Why are they gone? If you sat down with someone for a power lunch today, you might have an intervention in your future. Three Martinis used to mean serious business. Now it's a problem.
One of the "adults" we used to work with at Musicmaker was telling me once about how people who took the LIRR into New York would carry two thermoses with them: one full of coffee for the morning ride, one full of Bloody Mary for the evening ride. That doesn't sound like a bad plan to me. What better way to charge up for and wind down from your day at work, which for some reason, was a lot harder thirty years ago.
Why, also, are carpal tunnel syndrome and repetitive motion whatever new things? People in those old movies about being at work seem to be doing a lot more repetitive motion and a lot fiercer typing than we ever do. Maybe it was because they were so hopped up on caffeine that they didn't notice the difference. Or they were drunk.
