A cyclist climbs over a tree fallen atop a car after a heavy storm in Amsterdam, the Netherlands, July 25, 2015. One person was killed as the most severe July storm ever recorded in the Netherlands swept across the country on Saturday, delaying flights and disrupting road and rail traffic. Dozens of flights were delayed at Amsterdam's Schiphol Airport and authorities warned travellers not to take to the road as gale-force winds and rain lashed the country, prompting the meteorological service to issue a “Code Red” warning.

During a jungle survival program February 20, 2013 taught by Royal Thai Special Forces in Sannapit, Thailand, U.S. Marines learned to catch cobras and drink their fresh blood, not to mention eat forest insects and pull the heads off of chicken. The training was part of Operation Cobra Gold 13, the 32nd edition of international military exercises hosted by the Thai. According to a U.S. Marines press release, Cobra Gold is the largest exercise of its kind in Asia and incorporates troops from five other nations in addition to the U.S. and Thailand. The Daily Mail reports that the Marines were invited to experience the local custom of drinking cobra blood after being taught to catch and kill cobras in the wild. As CNN notes, Cobra blood is believed to be a panacea and aphrodiasic in parts of Southeast Asia. In Jakarta, vendors can earn over $100 a night selling shots of cobra blood mixed with liquor.
