Crack your neck at your own risk

You may feel good when you crack your neck, but I suggest you a secod thought.
Think about when you enter into your 50s (or 40s if early)...
One morning when you go to the bathroom and do regular washing your face and hands and now you are about to gargle...
What if your neck wouldn't bend backwards to let you gargle well...? I mean if your neck somehow wouldn't go any further than being straight so that your month cannot look upward to allow you to gargle. Then you would need whole your body to lie down backwards just to gargle, and then move your whole bady back again to spit out the water into the sink.
Or, when you want to look what is on your left, it is usually so easy, just to move your neck to the left, but... what if you need to move your whole body to your left in order to look at what is on your left because your neck itself wouldn't just move to left by itself?
So, if you have to expect this thing happen one day in your 50s, do you still want to crack your neck today?
In case you don't have this problem today, it is already a very good enough reason to say to God, "Thank you!"
