Why Do We Need Shorts?

Shorts were a design generated by necessity as time went by/history. First we had full length pants,then we had specialized clothing for flying and hunting which became shorter and tighter for their purposes and then we had clothes for swimming or for leisure time. Over time the clothes were adapted for looks and design to what we now call summer wear or shorts. We have hiking shorts,biking shorts,running shorts, then we have swimming trunks(basically shorts made for use in the water). In my opinion the reason shorts came along were because people became lazy and by be more lazy they became more sedentary and by being more sedentary they became use to having what we call the comforts of life in which means they wanted to stay cool while sitting around so they started wearing less and less clothes to keep cool. Just my opinion.

Shorts were first designed to determine what constituted long trousers. Before shorts we just had trousers, or pants if your American (british pants are a completely different garment trust me). Then some bright spark decided he wanted some trousers (pants) that only came half way down his thighs and thought I know I'll call them shorts because they're not as long as pants.
