"Maybe Tomorrow" but Will it be Too Late?

Is this setting SO beautiful that you'd want to inhabit it for basically 2 years?  Someone did and was quite sedentary on the toilet

It triggered a question for me.  What is it that causes a person to decide that it is time to seek the services of a physical therapist?  We have tools to evaluate the readiness of a person to exercise... we have tools to evalute a person's level of fear... we have tools to screen for depression.  What's the final factor that determines "I need help?"  Is it a lack of tolerance for the current life situation?  Is it an inability to compensate any longer?  Is it finally a lack of denial of a problem?  Is there some sort of belief, as with this woman, of "maybe tomorrow?"  Maybe tomorrow things will change?  Maybe tomorrow will be different?

Answers to those types of questions might be nice to know.  There are quite a few patients that should be seeking the services of a physical therapist sooner than they do.
