X-ray Before Recovery

4.2 cm in this picture. But as you can se I hold in my abs and holds my breath so the real depth when relaxed is around 5 cm.

I can also say that I have reached a new record. I'm below 1 cm at the moment.

Note: It may look like two silhouettes in the photo but there is only one. The black rectangle that shines through is equipment used to focus on the right things. If you want to know all details I think the best way to do it is to ask an x-ray specialist or a doctor to have a look.
