Potentially Life Saving Idea..But

The NHS have announced that by 2030, every baby born in the UK could have their entire genome sequenced under a new initiative to 'predict and prevent illness' which checks for hundreds of genetic conditions and at first i thought what a great potentially life saving idea, but then i thought some more on it and saw some potential problems with it.
The genetic result will suggest a child has a higher probability of developing a certain disease later in life but us Humans have a tendency to suffer the psychological problem of hearing 'you might get sick' and hearing 'you will get sick' and acting accordingly which could have huge implications of how children are raised, how they’re treated and how they could see themselves as they age, almost like a patient in waiting.
There could even be treatment for diseases they never develop and real stress and psychological damage around an anticipated future of illness, we still bear the scars from Covid when we all thought we were going to catch it and the be a statistic read out in the Prime Ministers Daily Briefings
I still think it is a good idea but i struggle to see how the emphasis can be put on how being higher risk does not mean it is a certainty because you cannot change the way we think, and unfortunately we always think the worst.
