What disqualifies you from getting life insurance?

Key details about life insurance

For fully underwritten or simplified issue policies, factors like a terminal diagnosis, recent major surgery, certain high-risk occupations or hobbies, or a very recent serious health event can result in a decline or a higher-risk rate class, though every carrier's guidelines differ.
