"Flying off the handle," and "going up in the air" are phrases
originally inspired by our dear, delightful friends, the Thoracics.

Other types do these more or less temperamental things but they do not
do them as frequently nor on as short notice as this type.

The Human Firefly

A fiery nature is part and parcel of the Thoracic's makeup. But did
you ever see a fiery-natured man who didn't have lots of warm friends!
It is the grouch--in whom the fire starts slowly and smoulders
indefinitely--that nobody likes. But the man who flares up, flames for a
moment and is calm the next never lacks for companions or devotees.

The Red-Haired

One may belong to the Thoracic type whether his hair is blonde or
brunette or any of the shades between, but it is an interesting fact
that most of the red-haired are largely of this type. "He didn't have
red hair for nothing" is a famous phrase that has been applied to the
red-haired, quick-tempered Thoracic for generations.

You will be interested to note that this high color and high chest are
distinctly noticeable in most of the red-haired people you know--certain
proof that they approximate this type.

As you walk down the street tomorrow look at the people ahead of you and
when you find a "red-head" notice how much more red his neck is than
the necks of the people walking beside him. This flushed skin almost
always accompanies red hair, showing that most red-haired people belong
to this type.

The "Flash in the Pan"

The red-haired man's temper usually expends itself instantly. His
red-hot fieriness is over in a moment. But for every enemy he has two
friends--friends who like his flame, even though in constant danger from
it themselves.

Whereas the Alimentive avoids you if he disagrees with you, the Thoracic
likes to tell you in a few hot words just what he thinks of you. But the
chances are that he will be so completely over it by lunch time that he
will invite you out with him.

Desire for Approbation

To be admired and a wee bit envied are desires dear to the heart of
this type. Everybody, to a greater or lesser degree, desires these
things, but to no other type do they mean so much as to this one. We
know this because no other type, in any such numbers, takes the trouble
or makes the sacrifices necessary to bring them about.

Acts Indicate Desires

The ego of every individual craves approval but the majority of the
other types craves something else
