Drinking is necessary for human body in order to survive this harsh and painful world,you can start by grabbing a cup of water to grab a cup of water you need to walk to the sink and then turn on the faucet and put the cup under the running water and wait for it to fill mid-way, after you've done that your going to want to put the rim of the cup to your mouth and let a small amount of water enter your mouth, after you've done that your going to want to swallow the water. Congrats you've learned to drink water
