1.Group life insurance thru an employer group. Reasonably hi guarantee issue amount and can be taken with you (converted) if you leave employer. This is how I got all of mine. Like Norma says, if you become disabled while working, premiums normally are waived.
2. Voluntary plans thru employer, union, fraternal, etc. organizations. Often have some level of guarantee issue or graded benefit. Look around to see if any organizations you belong to have plans available.
3. Individual life insurance thru hi-risk insurer. Most agents have access to hi-risk carriers. This will be a "rated" policy and premium will be based on your health issues. After a period of time, it is possible to have the "rating" reduced or eliminated.
Normally, best option is #1.
