00:00.740 --> 00:02.629
So some qualification is when the

00:02.629 --> 00:04.796
records come through and they show for

00:04.796 --> 00:06.907
efficiency and basic water survival ,

00:07.190 --> 00:09.246
such as swimming 25 years across the

00:09.246 --> 00:11.870
pool or jumping off a tower simulating

00:11.870 --> 00:13.759
that they're jumping off a ship .

00:14.600 --> 00:16.656
There's a four minute sand surface .

00:17.440 --> 00:19.551
They floated performance to show that

00:19.551 --> 00:21.662
if they got tired in the water , they

00:21.662 --> 00:23.662
were able to just lean back , float

00:23.662 --> 00:25.662
pressure breath and get some energy

00:25.662 --> 00:28.290
again . They had a 12th year should ,

00:28.710 --> 00:30.766
which means that they basically were

00:30.766 --> 00:32.877
ableto get rid of all their year that

00:32.877 --> 00:35.099
they had on their body in order to come

00:35.099 --> 00:38.990
back up . Who struggle with the most

00:39.000 --> 00:42.060
is saying relaxed in the water . They

00:42.060 --> 00:44.270
don't understand the concept of

00:44.410 --> 00:46.410
explosive breathing and making sure

00:46.410 --> 00:48.577
that they have full long inflation and

00:48.577 --> 00:50.466
that they just want toe , relax ,

00:50.466 --> 00:51.150
calmer they are , the further they go
