Today there is so much that we can find out about ourselves. It has become popular to have you DNA done and discover you roots. (if the tests are accurate) You can be tested to see if you have the gene for breast cancer or find out if you are likely to get Alzheimers. Each day there is something new.
My father had kidney stones and you can inherit the tendency to be a “stone makes.’ This is someone who has stones from an early age. I inherited that. We can also check to see if we have genes for some diseases that might make us choose to not have children such as Cystic Fibrosis. I suspect that as time goes on we will face some moral dilemmas and have to make some uncomfortable decisions.
Hopefully we will not reach a point where the choice is taken out of our hands but it is not impossible.
I do wonder if I knew that there was a possibility I would pass on anxiety and depression what I would have decided. The thing is you wouldn’t know if descendants would have a mild problem or a serious one.
I don’t think that any of us would want to pass on something negative to our children and grandchildren. Sometimes too much knowledge is a dangerous thing.
