Strange Wonder #2: Giraffes are Insomniacs

Giraffes only sleep 10 minutes to 2 hours in a 24 hour period. Sleeping for giraffes is dangerous and a bit awkward. Most of the time is spent standing but it must lay down when dreaming (about 20 minutes.) Its take a giraffe over a minute to stand up which makes it vulnerable if attacked.
There is no set human time for needed sleep but on average, humans sleep 7.75 hours a day.
The current world record for the longest period without sleep is 11 days, set by Randy Gardner in 1965. Four days into the research, he began hallucinating. This was followed by a delusion where he thought he was a famous football player. Surprisingly, Randy was actually functioning quite well at the end of his research and he could still beat the scientist at pinball.
