Dear Scientist, Engineers, Physicists, and Physicians:
You probably received this letter from an organization requesting your opinion on our contentions that children develop
finger deformities from video gaming and should not play until at least 8 years-old. This is posted on our web site www.
miketomich.com. We would appreciate you reading the engineering message in this letter and I’m sure (with the lack of
a formal scientific study) you will agree that our contentions should be taken seriously and they warrant further study
Throughout history, science has continued to witness the development of bent and twisted arthritic fingers, joints,
chronic back, neck, shoulder, hip, knee pain, the recent carpal tunnel syndrome, but has failed to recognize the one
simple root cause of these injuries, and many more injuries.
Simply put, our human skeletal system has a “MATERIAL CREEP” force tolerance threshold value. The same “Material
Creep” formula (that is used as a standard consideration when calculating suitability of any load-bearing component
expected to experience long-term loads) does also fully apply to the human skeletal system. I have witnessed the stress
at which the children’s soft bones have entered their plastic range (see note #1).
The human skeletal system is a structural engineering marvel and as with any structural design; there are physical
limitations. We have linked internal and external generated physical limitations to children and adults soft tissue and
Up until now, it appears as if that standard policy has not been recognized by the medical industry and very little, if any,
consideration for material creep has been considered in the design of items that place stress on bones and joints.
Basic knowledge of this subject and experience tells me that material creep can occur in any free molecule or cellular
based material, including bones with their variances of length, diameter, and a major factor of bone hardness
(calcification strength), and the speed/velocity of force generation and delivery. Thus, it is logical that some toys and
activities of children result in skeletal stress and some of these stresses may lie within the plastic range of bones. It
appears as if this negative impact has not been considered and there have not been studies to substantiate or negate this
highly likely detrimental impact on the skeletal system.
Although bones are like any other cellular material and as such, material creep stresses can impact the ability of the
skeletal system to properly and painlessly function on a long term basis. The exact negative impact upon our child and
our adult health cannot be evaluated without a major scientific study that will encompass the variables of bone size,
calcification, and force generation and delivery relative to performing various processes. Such a study is well beyond our
In lieu of the lack of a full scientific study…I think the most you can recommend at this time is that “our contentions do
warrant further study, and precautions are advisable.”
Thank you for your consideration.

Note #1 (Plastic Range Definition: (DOD, NATO) The stress range in which a material will not fail when
subjected to the action of a force, but will not recover completely so that a permanent deformation results when
the force is removed).
