It was the saddest, most desperate feelings I’ve ever felt. Tonight I’m back play Otto bar and celebrate the death of that hopelessly desperate and selfish give thanks for this new life I’ve been trying to build with my friends and family. Don’t ever give up on yourself. You can change anything about your life that you don’t like, give your pain a purpose and make it meaningful. Believe in love and its healing powers. Sing and dance everyday and listen to the poor please who love you. #reallove #realmagic”

Long jump, like many track and field events, is affected by fluid dynamics in subtle ways. Both wind speed and altitude can modify a jumper’s performance - first, by changing the maximum speed they reach in their sprint, and second, through aerodynamic drag while in flight. Air resistance accounts for roughly 10% of a sprinter’s energy expenditure. A slight tailwind gives an athlete a minor boost in speed that can translate into a more significant increase in jump distance. On the other hand, though, a headwind of the same magnitude has an even stronger negative effect on performance.

The other factor, altitude, comes into play through air density. The official Olympic record for the long jump was set by Bob Beamon in the 1968 Mexico City Games. The high altitude of Mexico City results in an air density that’s only 75% of that at sea level. That’s tougher on athletes in terms of oxygen levels, but it’s a big reduction in the overall drag they face, resulting in both a higher sprinting speed and less aerial drag. This is part of why Beamon’s jump stood as a world record for well over 20 years! (Image credits: AP Photo; AFP/GettyImages; Reuters)

Senator Ted Cruz

not being likeable enough or having the right “temperament” to be President, in an interview with Fox News Channel’s Chris Wallace.

I mean…you can’t tell me that Trump is not just fucking with us! Donald Trump accusing Senator Cruz of acting “like a little bit of a maniac” is like Donald Trump calling someone out for having a bad combover and wearing too much television makeup. Trump has successfully figured out how to run for President like a YouTube troll.
