The seal of this joint is less vital than the tip, but it'll still seal for at the least three seconds. A good test to check the natural place of your hand, and as a result reveal where
the thumb rest might be, is to hold your right arm by your side. Both the arm and hand might be undoubtedly comfortable. Being wary
not to maneuver the thumb, bring your hand up to gambling place. Notice how the thumb rest is far lower than the comfortable place of the thumb?Try to head the arms in a rapid motion with the thumb in the cozy place. Now bring the thumb down to the position of the thumb rest and move the arms abruptly as before.
