Are there other issues besides health?

Yes, there is the issue of Human Life Value, which has to do with the formulas Life Insurance Companies use to determine how much they can insure somebody for. You can’t insure someone for a ridiculous amount of money, for instance, a 20-year-old making $20k can’t get approved for $5 million. For more on Human Life Value and also supplementing with term insurance, see our post on “How Much Life Insurance Do You Need?“
