Totally Disagree there. I use a backpack a lot now since I can't walk very good until my upcoming knee surgery. I am either on crutches or a cane and have a time carrying a handbag. Saying its weird is unfair.. KWIM
Good luck on your upcoming knee surgery!
I have to agree that backpacks definitely have their uses. Having had 4 knee surgeries and a fractured foot over the years they were total lifesavers. Not to mention very useful when touring wineries and juggling wine glasses.
