How much do you consider your family history (or gene testing, if you've done it) when making lifestyle decisions?
For example, if you find out tomorrow that many of your older relatives had/have a particular cancer, would you begin to make decisions to protect against that cancer, or would you be comfortable in keeping with a generic mantra of "eat paleo, get plenty of sleep, lift heavy things" type of attitude?
If you have used 23andme, or a similar service, how much weight do you put into the results? For instance, if your report reveals you have a gene that puts you at risk for depression (just an example; I don't know if this even exists), despite no depressive tendencies, would you alter your choices to actively avoid depression?
Why I'm asking:
I recently learned of certain conditions that are prevalent on one side of the family (Alzheimer's and breast cancer) and I am struggling with what steps--if any--I should take against these (potential future) conditions. I am going back and forth with this: should I live life as normal or battle against these diseases with everything I have, despite not actually having either condition?
I have not had genetic testing done, but am curious as to what type of additional insight I could glean from it.
What is your stance?
