Dentist: Dentists are always trained to be very meticulous. All of them expect them to do things "perfect". So, this will be a hell lot of pressure on them and this stress can be overwhelming and can lead a person to commit suicide, if they feel they are not as "perfect". However, a research conducted by Rogere Alexander from American Dental Association found that there was little valid evidence that dentists are more prone to suicide than the general population. According to NIOSH, Dentists were 1.67 times more likely to commit suicide and they recorded 148 suicidal cases in this field. Veterinarians: It seems a bit surprising for all of us that veterinarians are four times as likely to commit suicide than the average person and twice as likely as our human healthcare counterparts. This dark fact was brought to you by the series of United Kingdom studies conducted over the past few years. Many of us don't realize the fact that many vets may be more sensitive. The three reasons for a vets stress would be because of the number of working hours, making professional mistakes and the client's complaints and allegations. According to NIOSH, veterinarians are 1.54 times more likely to commit suicide.
