Jump

I heard someone mention wearing a life jacket to improve the odds of surving a high jump into water. That's just not the case.

When jumping into water, please do not make the mistake of wearing a life jacket. Once you jump into the water, whilst your body will be trying to go down, the life jacket will be pulling up with an extreme amount of pressure.

Depending on the type of life jacket and how lucky you are, it might end up strangling you, heavily injure your groin area, cause immense stress on your back and neck, as well as many other interesting options.

However, if you're bad at swimming, you might want to risk those injuries.
