Interesting fact about life and moon.
HOW MANY ORGANS COULD YOU LOSE AND STILL LIVE?
You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs. Losing your uterus, ovaries and breasts, or your testicles and prostate, is also quite survivable, although you might need hormone therapy to avoid other long-term problems, such as brittle bones. If you allow yourself artificial replacements and medication, we can go further and remove your stomach, colon, pancreas, salivary glands, thyroid, bladder and your other kidney. Still not enough for you? Theoretically, surgeons could amputate all of your limbs, and remove your eyes, nose, ears, larynx, tongue, lower spine and rectum. Supported by machines in an intensive care unit, they could also take away your skull, heart and your remaining lung, at least for a short while. This adds up to a theoretically survivable loss of around 45 per cent of your total body mass. But any trauma that destroyed all these organs all at once would almost certainly kill you from shock and blood loss. And surgically removing them one at a time over many months would likely also be fatal, due to infections in your immune-compromised state.
Why is the Moon colourless?
Despite appearances, the Moon is not entirely devoid of colour. Apollo astronauts described its colour as ‘brownish’. Careful study shows that the dark areas, or ‘maria’, display hints of blue or brown while the highland areas have faint traces of yellow, pink and pale blue. These differences are mainly due to varying amounts of metals such as iron or titanium in the surface minerals. Unfortunately, the human eye isn’t sensitive enough to pick out these slight differences in colour from a distance. However, much of the lunar surface contains minerals that are naturally grey and these dominate the colour we perceive from Earth.
