Many health conditions are known to run in families. These include heart disease, high cholesterol and blood pressure, diabetes, asthma and other allergies, arthritis, Alzheimers and other dementias, depression and several of the most common cancers.

It makes sense then that there will be a relationship between the Bio-Age profiles of family members. It also means that the Challenge Profile answers and daily tracking data you give here will contribute real value when generating goals and recommendations for your blood relatives. And vice-versa.

Often, younger extended family members don't know their blood pressure and cholesterol numbers. If this is you, data from a close biological relative can make your Bio-Ages and recommendations more accurate. If you're a little older, your answers can have great value in predicting the health future for younger biological relatives. Your contributions might even result in lifestyle changes that will significantly improve that relative's quality of life.

When you invite family members to take the Bio-Age Challenge, you make all this possible. What's more, you'll be helping to create the largest-ever pool of anonymous data about family health relationships. That's knowledge that will ultimately benefit everyone.

Invite your family to take the challenge. One day they may thank you for it.
