The calculations are based on complex data from the UK Pensions Industry* - but it's important to know that your results aren't set in stone - they are just an indication of how long you are likely to live.

These definitions will help you:

Excellent health: - assumes that you are feeling pretty good and haven’t been to the doctors for as long as you can remember. Your height and weight are fine, and you don’t take any tablets for any health conditions.

Reasonable health: - assumes that you are feeling okay health wise, but not brilliant. You have managed to give up smoking, and you take medication for Type 2 Diabetes.

Challenging health: - assumes that your health is struggling as a result of a more serious condition such as Parkinsons that is impacting on your activities of daily living.

Critical health: - assumes that you are suffering from a very serious medical condition, such as cancer, and undergoing treatment for it. You may find it difficult to get about, and possibly need assistance with day-to-day activities.
