Courtroom lawyers have higher testosterone levels than their colleagues in
less confrontational jobs, a new study has found. In animals, the hormone is
linked to aggressive behaviour. A team led by James Dabbs, a psychologist from

male and 31 female barristers and found both sexes had about 30 per cent more
testosterone than lawyers who did not plead in court (Journal of Applied
Social Psychology, vol 28, p 82).
