Fuck if I know where to put this post.
School is starting up for me in a couple weeks after this summer term finishes.
Anyway, I usually take a notebook, a water bottle, my wallet, a pen, a book (for personal reading) and a journal. To carry all that crap, I take a messenger bag and wear it across my body.
I haven't experienced any problems with my shoulders bothering me, but I'm trying to correct some postural problems (pretty bad kyphosis and lordosis) and was wondering if using a backpack would be better.
Any suggestions that can give a good physiological reason as to why one would be better than another?
