How Big Should A Business Be Before The Owner Finally Delegates Responsibilities?

I am in the family business and my mom is clearly strained… We are blessed to have business hand over fist even in this recession but that is not my problem, or question… My question is how can a small business owner learn to lay back enjoy the fruits of their labor??? I mean she has owned this insurance agency for 30 yrs. and has nursed it from ONE policy to what it is today? But her health is declining as she is still trying to take payments, pictures of homes, etc. on what should be considered now at least a “mid sized” business?
