I think you would have to two scenarios at hand: 1. A completely genetically determined disease; a rare 100%-going-to-happen deal. (Which you would probably know about already, because your mother, or grandfather died from it...) 2. Some significant, but abstract risk modification. With 1., you would know, you will get sick/die some time soon in the future, allowing you to live your life accordingly, die without regrets, prepared and so on. You can take that into consideration when planning for a family, taking job offers, procrastinating on the good life with work and retirement plans. Burn bright. With 2., there is a very, very high chance lifestyle choice influence the stated risk, as obviously not everybody who got the polymorphism gets sick. So you can get your ass up, exercise, quit smoking and drinking, reduce stress, get regular check ups, ..., and avoid getting sick or reduce the impact/progression, in case you do. I think, logically, knowing is always better than not knowing. But I understand how anxiety does tell a different story. |
