Do you know of any teachers that became lawyers?

I am 31 years old going on 32 and I am currently a teacher teaching in Elementary School. So far I have 4 years of teaching and truthfully I love the job, but I was thinking of taking another degree in law to become a lawyer. Some people say it is a good idea but there are some doubts that are in my mind: 1. Am I too old to pursue this new career? 2. Are there any teachers that you all know of that left teaching and went into law school? 3. I would be doing that law degree part time which is 5 years would that interfere with me having a family? 4. Is there a field that is within law that would allow me to work with children?
