A relatively light topic for scientific investigation, to be sure, but in her write-up, Dillon defends her inquiry with some surprising heft, quoting a 1970stome about the calming powers of touch: "In ancient Greece it was customary, and is still in so much of Asia, to carry a smooth-surfaced stone, or amber, or jade, sometimes called a 'fingering piece.' Such a 'worrybead,' as it is also named, by its pleasant feel, serves to produce a calming effect. The telling of beads by religious Catholics seems to produce a similar result." Dillon adds that keeping your hands busy with little projects like needlework is considered relaxing, and suggests that attacking a sheet of Bubble Wrap might work in the same way.
