I always tell people not to give your email or phone number to anyone on the street offering a free stress test. I promise you they will use that unpaid workforce and call, text and email you every single day. Another person I would suggest not giving your phone number to is this A-/B+ list actor who has had more misses than hits, but all of you know who he is. For the past several years, every woman who has gone out with him has said that he is abusive. It can be verbal or physical or both.
