Im nearly 50 years old ,, am i to old to start martial arts what do you think would b the be est for me?

You are never too old to start martial arts. So long as you can walk you can train. the best approach is to simply Google a list of schools in your area. From here, compile a list of arts you feel are the most interesting or that you like the most. Once you have this list down, go visit the local schools of the style of your choice. While visiting these schools, make sure the instructor is knowledgable and that the school is not a McDojo. Once you have visited all the schools in your area and you have a good list of schools, decide which school you like the best or which one is cheaper, or closer, etc.
