But the minor aches and pains of today can cause long-term damage tomorrow. Once that is in place, it's very hard to get rid of. The problems caused by years of toting heavy backpacks can take just as long to go away naturally. Most times though, due to the resilience of young people, students heal quickly. Most wouldn't consider a chiropractor for mere backpack-related woes.
Balance is important.
Students should keep weight evenly distributed and use both straps. No matter what grief they cause, students need backpacks. Common sense can usually save some aches and pains. Carry only what you need. Stretch out before a long haul with a heavy bag.
