Little things people tend to take for granted

Many of you might not realize them, but there are so many little things in this life which are so great and beautiful. For example,

1. Breathing. Have you ever tried to realize your breathe? Breathing is so great! If you're not breathing than you're dead. Most of the time because we're so busy in this life, we completely forget that we're breathing. Try this, every time you come home from work, or school, or anywhere, in some point on your way home, STOP! Just stop, close your eyes, and take a deep breath. Feel the air coming to your nose and lunge. You'll feel great!
2. Sneezing. You think I'm kidding? No, I'm f**king serious. Sneeze is one of God's greatest miracle. Have you ever felt like you're going to sneeze but you CAN NOT!??It's painful! And it feels so damn great when you are able to sneeze and let go of everything inside! Just so you know, we really need to be grateful for this so called "sneezing" ability. It means you're healthy, your body is responding because maybe there's some unidentified and dangerous object entering your body through your nose by sneezing so that that object can be blown away. That's why muslim people always say "Alhamdulillah" every time they sneeze which means "All praise belong to God". Good for them.
3. Taking a pee. Oh My God, when you can not pee, you can not move, you feel pain in your stomach area. But when you can release it, wooooooooooooooooooooow, a greatest feeling. Be grateful of it.
4. And many more.

Even if you are the richest human in the world, if you can not breath, sneeze, or take a pee, you'll suffer a lot. So be grateful of little things in life. Any idea what else?
