Do you crack under pressure? Crumble when you’re stressed?

If so, you’d be better off pursuing a career in science or education than you would in healthcare or law enforcement.

Using data from the US Bureau of Labor Statistics and O*NET OnLine, career-information expert Laurence Shatkin, Ph.D., helped Business Insider rank the 767 occupations identified by the US Department of Labor by “stress tolerance.”

The “stress tolerance” for each job is a rating on a scale from zero to 100, where a lower rating signals less stress. It measures how frequently workers must accept criticism and deal effectively with high stress on the job.

Here are 27 jobs that earned a stress tolerance rating of 93 or higher. If you’re the type of person who thrives under pressure or can stay cool, calm, and collected in high-stress situations, these jobs may be perfect for you.

If you’re the crack-or-crumble type, you may want to avoid them.
