People believe that nail biting is just a sign of nervousness and anxiety. Even though this might sound unbelievable to you, nail bite can be a cause of many other problems and sometimes it could even have a fatal ending like death.
The man who couldn’t stop biting his nails is John Gardner who is a 40-year-old man and still has this bad habit. Even when the doctor prohibited him to bite his nails, he continued doing that which led him to a painful septic infection and a heart attack.
As Dr. Vernon explained, John’s nails were always in a poor condition and they were bleeding very often.
