It also indicates a highly nervous, easily excited individual, one who has little control over himself or his temper, who is easily put out over trifles, and liable to do the most erratic things, or fly off at a tangent when irritated.

Such people are always in trouble, generally fighting or quarrelling with those about them and over things that are of no consequence.

They are likewise so easily wounded in their feelings, that even a look or an imagined slight will put them out of humour or upset them for days.
If this Line of Head farther out in the palm become straight, it denotes that the subject will, later, by the development of his intelligence largely overcome this failing of over-sensitiveness.

If the line slope much or bend down towards the wrist or on to the Mount of Luna (the Mount of Imagination), then the subject will become still worse with his advancing years.

If the Line of Head is also poorly marked, or with "hairlines" from it, it is often the indication of some form of insanity which is likely to cause the subject to be placed under restraint in later life.
If, with this latter indication, the student also finds all the upward main lines, such as the Line of Destiny, etc., fading out past the middle of the palm, the indication of insanity and restraint becomes all the more certain.
This class of Head Line is largely found in cases where the subject is naturally inclined towards drink and intemperance of every description.
Even in cases where there are good lines running up the palm, it will usually be found that the subject gives way to occasional fits of intemperance or the desire for drugs.
