Disabilities can occur at conception as a result of coincidental occurrences in the uterus.
They can even be predetermined long before conception through the genetics of parents. Once born, all human beings are then subject to a myriad of disabling possibilities for the rest of their lives.

The most fundamental implication at the personal level is that disabilities can happen to anybody at anytime. The most fundamental implication at the family level, is that the disability of one family member will affect all of the other actively engaged family members.
