So even if you're hanging on to life by the thinnest of threads at renewal time, you'll be able to keep your insurance. Many younger people favor term insurance during their 20's and 30's. After all it is cheaper. But as you get nearer to forty you'll probably want to consider 'permanent insurance'. With this type of insurance, as long as you continue to pay the premiums you'll have coverage no matter what your health condition.
Permanent insurance goes by a variety of names.
Basically, they're all variations on the same policy. One of the most common is called 'whole life'. Here you'll pay a consistent premium for the rest of your life. The premium is split into two parts. One part actually pays for the life insurance for that year.
