Normal men do not typically loose interest in sex altogether. Even 77 year old men still have at least some interest in sex. If a man looses his sex drive altogether that could be a sign of any number of possible issues. It could be psychological, like the death of a wife or girlfriend or something that affects a guy mentally.
In a normal adult the red cells of about half a litre (almost one pint) of blood are produced by the bone marrow every week. Almost 1 percent of the bodyâs red cells are generated each day, and the balance between red cell production and the removal of aging red cells from the circulation is precisely maintained. The rate of blood cell formation varies depending on the individual, but a typical production might average 200,000,000,000 red cells per day, 10,000,000,000 white cells per day, and 400,000,000,000 platelets per day.
Red blood cells carry nutrients and oxygen to the body's cells. Red blood cells are come from bone marrow. White blood cells help the body fight diseases and infections. The white cells are made in the bone marrow. Plasma is the watery part of the blood.
