hi, im thinking about joining the army but i m afraid that when i join the army, the army is going to make me carry army gear on my body that will weight about 70-100 pounds, and i m afraid wearing that much body gear will cause me to become shorter. i m already short and i don t want to lose any height. so please, be honest with me, would carrying 70-100 pounds of body gear such as helmet, backpack, armor, rifle, boots, and clothes everyday while running and walking. Would that cause my spine to decompress and cause me to get shorter? And I also have a slight curve in my spine, would carrying 70-100 pounds daily while running and walking cause my spine to curve more? Lastly, would running everyday cause my spine to decompress? My friend told me running a lot can make someone shorter, is that true? Simply put, would carrying 70-100 pounds everyday while running and walking for long periods of time put me at risk of getting shorter? Please answer all of my questions..thank you
