temperaments are they true?

I tried this test on www.oneishy.com and according to that site, these two are my temperaments: I am a SANGUINE PHLEGMATIC

Sanguine
Sanguine indicates the personality of an individual with the temperament of blood the season of spring (wet and hot), and the element of air. A person who is sanguine is generally optimistic, cheerful, even-tempered, confident, rational, popular, and fun-loving. They can be daydreamy to the point of not accomplishing anything and impulsive, acting on whims in an unpredictable fashion. Sanguines usually have a lot of energy, but have a problem finding a way to direct the energy. This also describes the manic phase of a bipolar disorder.

Phlegmatic
A phlegmatic person is calm and unemotional. Phlegmatic means pertaining to phlegm, corresponds to the season of winter (wet and cold), and connotes the element of water.
While phlegmatics are generally self-content and kind, their shy personality can often inhibit enthusiasm in others and make themselves lazy and resistant to change. They are very consistent, relaxed, and observant, making them good administrators and diplomats. Like the sanguine personality, the phlegmatic has many friends. But the phlegmatic is more reliable and compassionate; these characteristics typically make the phlegmatic a more dependable friend.
