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 Occupational Information Network (O*NET), a US Department of Labor database full of detailed information on jobs, we found the 29 professions you should avoid if you really don't like stress.

O*NET assigns a "stress tolerance" score (0-100) — which measures how frequently workers must accept criticism and deal effectively with high stress on the job — for each of the almost 900 jobs in its database. A lower rating signals less stress; a higher rating signals more.

Here are jobs that earned a stress tolerance rating of 94 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.
