11cxkb | why is it so hard for our body to handle a cold? | Ever when I get a cold, it takes at least one week to deal with it, sometimes even two. Taking medicaments doesn't push on the healing, just makes it more bearable. Why does it takes us so long? Why don't we develope something to immune ourselves?
