Virgos are often tender but also very careful. Virgo is an Earth sign, which prefers conservative and organized things, and those dependent on them. People born under the Virgo sign have very organized life, and even if they are very messy, their goals and dreams are put on strictly defined points in their mind. Since Mercury is the ruling planet of Virgo, this sign has a well-developed sense of speech and writing, as well as all other forms of communication.
From Wikipedia, the free encyclopedia. Randy Gardner (born c. 1947) is the holder of the scientifically documented record for the longest period a human has intentionally gone without sleep not using stimulants of any kind. In 1964, Gardner, a 16-year-old high school student in San Diego, California, stayed awake for 264.4 hours (11 days 24 minutes). This period of sleeplessness broke the previous record of 260 hours and 17 minutes held by disk jockey Tom Rounds of Honolulu.
But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and that extends that period of time. The longest contiguous amount of time a human has spent in space is 437 days. That was done by Valeri Polyakov, almost twenty years ago. That was his second flight. His first was 240 days long. Sergei Krikalev, over six flights, has spent 803 days in space. Space is a harsh environment for humans.
