Great news! You are in your fifties (50's), so getting affordable life insurance rates is still possible.
If you are if fairly good health and have to major health issues like, diabetes, heart problems, hypertension (high blood pressure), cancer, etc., the life insurance companies are more than happy to insure you.
Remember, to get the best policy rates you will have to submit to a simple medical exam.
A medical professional will come over your house to examine you and draw blood for tests.
If all is okay with you and no major issues were found, then the insurance underwriter will give you the final policy costs.
It's best to always go with a medical test and not get a policy without a medical exam. These are priced much higher.
Other things to keep in mind are:
The good news is, you have control over if you smoke or if you are overweight. So, quit smoking and lose some weight before getting a life insurance quote.
