In comparison with most other mammals, humans are very long lived[10] with an average age at death in the developed world of nearly 80 years old.
[11] Humans also have the longest childhood of any mammal with sexual maturity taking 12 to 16 years on average to be completed.
Similarly human sense of touch is well developed especially in the hands where dextrous tasks are performed but the sensitivity is still significantly less than in other animals, particularly those equipped with sensory bristles such as cats.
It makes use of various scientific methods, such as experiments and observations, to detail the biochemical and biophysical foundations of human life describe and formulate the underlying processes using models.
Similarly, human life requires a range of vitamins to be present in food and if these are missing or are supplied at unacceptably low levels, metabolic disorders result which can end in death.
Many of the organisms associated with human biology are the specialised biome in the large intestine and the biotic flora of the skin and pharyngeal and nasal region.
Many of these biotic assemblages help protect humans from harm and assist in digestion, and are now known to have complex effects on mood, and well-being.
These communication skills enable civilizations to grow and allow for the production of art, literature and music, and for the development of technology.
