I don't think it is likely that you'll spontaneously develop Tourette syndrome, because that is caused by a birth defect, as far as I know. You can, of course, develop a tic that mimics Tourette.
Tics are learned behaviors. They're likely to form when you are under a lot of stress from, say, a depression. On the up side, with discipline you can most tics under control.
If you do have Tourette, a little discipline will go a long way to get that under control as well.
