If you don't lighten your pack, you could get a hunch back.
Straighten-up! Unless you want to be leaning all your life, lose some of the load off of your shoulder.
Get the lead out of your pack! And always bend your knees to lift. If you don't, you'll be heading for back trouble.
That load'll seem a lot lighter if you pick a pack with plenty of compartments.
You've got two shoulder straps. Wear'em both. Place your pack on the table, and put it on one strap at a time.
Carry the heaviest items closest to your body. Use your waist belt, and adjust the straps.
