Knowing what life has in store for us

Living with uncertainty is not an easy task. It can be the source of many anxieties.

I often go through this with my patients, for example when we may have found something sinister but more time is needed to confirm the diagnosis.

Yet, when it comes to our lives and deaths, we always live in uncertainty. But what about the opposite: what if we knew what life has in store for us?

Chloe Benjamin deals with this theme in her book The Immortalists.

At the beginning of the story four young siblings visit a fortune-teller who gives them the dates when they will die. This knowledge influences the rest of their lives and the choices they make. It becomes a self-fulfilling prophecy. Three of the four siblings die on the predicted date, largely as a result of their own doing.

I wonder if the information increasingly available through genetic testing will influence our lives and deaths in a similar way. Would we live our lives differently knowing what may be ahead of us? Could this knowledge also create its own anxieties and problems?

Here are five things to consider before ordering a genetic test.
