  1. Interesting, but the count of 91 is exagerated. Some of the facts are repeated or re-phrased and others contradict each other. For example: The info in #74 was already said in #73. #9 and #69 basically say the same thing. #12 really has little to do with human anatomy. The length of the small intestine is different in #50 and #68. etc…

  2. Once i read in one of the newspaper that the weight of the soul is 21 gms.This measurement is taken before and after the man dies— keeeping the man into a glass house before and after and the difference they found 21 gms . i was searching this information since long time. any way i got it Thanku.

  3. A large number of these “facts” are not true. Careful where you get your resources and what you claim as fact.
    …maybe more of us should have payed attention in school on how to do credible research.

  4. You should be made aware that the layer of skin that exists only on the palms of the hands and soles of the feet is the STRATUM LUCIDUM not the Stratum Corneun, as that is the most superficial layer of all skin.

  5. is it all a fact do they have proof ? sexual intercourse is ten to fifteen minutes again it depends on the stamina of the involvers
