I admit I have thought a lot about this topic and I’m so happy to see some thorough research on it. Good job, Slate. And thank God for everyone involved in the change to two shoulders. So much more comfortable.
[I remember being in middle school and wearing my backpack on two shoulders after school one day to get a laugh. I’m pretty sure it mostly had the desired effect, but I distinctly remember Megan shouting at me to make it stop because the overwhelming nerdiness of the spectacle was too much for her to bear].

I believe we’ve discussed this several times. Along with rolling my pants, one-strapping was imperative. Strangely though – I’ve been thinking about this lately – wearing jeans with a jean jacket was OK.
Ha!
Proof I never knew what was cool or not. Or sensible or not. I hope I’ve improved my sense of the latter, at least.
Disagree! You were scoring an A+ on the cool factor, which was all that was under review at the time. It was another 6+ years before the tide started to change … You were right on the money. I wonder, though, whether it’ll change again someday…. Such an odd thing.
