Suicide rates appeared to increase with increasing hours of daylight,
and showed no connection to other meteorological factors such as
changing temperature or rainfall.
Surprisingly , sunlight is known to indirectly induce heightened brain
levels of serotonin, a biochemical inversely linked to depression. The
lower the levels - the deeper the depressive episode. Serotonin drops
during winter months.

Tapeworms
Tapeworms affect not only the digestive tract - but also the liver.
They range in size from 1 millimeter (0.04 inch) to a whopping 15
meters (50 feet!).
They are found in almost all vertebrates, including fish. Many of them
have distinct heads and bodies. None of them has a mouth or any trace
of a digestive tract. They absorb their food rather than digest it.
Tapeworms are hermaphrodite - i.e., each individual is both male and
female. They fertilize themselves. When "pregnant" each
tapeworm contains hundreds of thousands of embryos.
