Since March, when the Syrian refugee community attracted international attention because of its sheer size, their number has continued to climb. More importantly, the rate of that increase has hastened. In the last six months of 2012, a typical update from the UNHCR consisted of about 2,300 newly registered refugees. In the first six months of 2013, an average update had 7,300 refugees. Today, the UN has registered more than 1.6 million refugees and acknowledges more than 200,000 who still await registration.
The longest time to hold the breath underwater with pure oxygen prior to the attempt was 22 min 32 sec by Goran Äolak at the Zagreb main square in Zagreb, Croatia, on 29 September 2013.
The researchers believe the finding may explain why some sea mammals are able to make such long underwater dives while other mammals can only hold their breath for a few minutes. Sperm whales make some of the longest dives achieved by mammals, with some lasting up to 90 minutes, while dolphins and other whales can stay underwater for 20 minutes. The longest time a human has held their breath for under water is 19 minutes â set by a Swiss freediver called Peter Colat.
