Freediving

Freediving is an extreme sport and it's about suspension of breathing voluntarily.
This sport is the opposite of all sports because in the freediving isn't about physical training. It is about relaxation of all organs and muscles for don't spend so much oxygen, and this is more difficult. Freedivers before doing freediving they do relaxation exercises.
Freedrivers wear ballast to not float so much and this way they can stay motionless in the water. This ballast can change depending on the depth and the weight of this person.

The other trouble is pressure. How do they go down 50 to 100 m?
They have two ways:
1-The traditional way:
Everybody knows this way, we put the fingers on the nose and put pressure, when you feel ears hurting you kick off the air from the nose. But this way in the long run is harmful for your ears. Also this way you can not go down so far.
2-Frenzel:
This is the way all the professionals freedivers use and has three parts:
Step1- Mouth fill
Step 2- Close your throat 
Step 3-  Use tongue as piston
If you do well you can feel air going to your ears.

But this sport has many risks, the most important risk is the syncope.:
It's like fainting. The  syncope comes from of scarcity of oxygen in the brain.
If you have a syncope you can lose one of the senses. One professional had a syncope and he lost the taste sense for one year.

When I was little my dream was to fly and when  I am alone and in complete silence, floating in the marine bottom it's like flying. This is why my favourite sport is freediving.
