Thumbs up is a universal sign of approval.But holding your thumb up can give you a clear picture about your personality. Checking the angle of the thumb can give an indication about your personality.
In the crooked thumb you can see, the back of it curves. It can curve a lot or a little, depending on the person.
A crooked thumb mean you are so much expressive you want to express your feelings with all and put yours thought out.
Some people have a straight thumb when they give a thumbs up. There’s no bend to the bones at all, and the thumb doesn’t even slightly retract backwards over the knuckle. The straight thumb could mean that you’re a more serious person than most. Though you don’t show your excitability, it doesn’t mean you’re a downer.
A person whose thumb makes an obtuse angle with the index finger is a gem. Such thumbs are well-built, long and lean. They are called tender thumbs. People who have such thumbs are calm and thoughtful. They usually make great artists and musicians.
THE FIRST HALF IS LONGER THAN THE SECOND HALF
Unlike the fingers, your thumb is divided into parts. Now if your first half/upper phalange (biological term for bones of the fingers and thumbs) is longer than the second phalange, then you are driven by a strong sense of will power.
Check your thumb, because this means that you are a hard-working person with an iron will! In matters of love, you are 100% dedicated, and you are extremely faithful.
THE SECOND HALF IS LONGER THAN THE FIRST HALF
If the second half is longer than the first one, then you make all your decisions based on logic, instead of will power. You tend to restrain yourself when it comes to falling and feeling in love, and as a result you may miss out on dome golden opportunities to find a suitable life partner.
