This thread isn’t about a man in his forties, it’s about a man who will be at least 58 when the child is born.
A very active role is being there, being involved. He has only 20% chance of living to ninety, so it probable that he won’t be around to play an active role beyond the child’s thirtieth birthday. This could mean he isn’t there for weddings and Grandchildren.
He has a sixty percent change of reaching eighty, so slightly better than even odds that he will be there there for university, driving lessons, first flat share, first serious romances etc.
There is a good chance he will live into his seventies - the teen years. However he will be elderly, and much more likely to experience ill health at this age, a lot of difficult diagnosis unfortunately increase after 65.
People will jump up and down and some examples of very young people who become ill and very old people who are in fantastic health. But they are outliers.
It is less likely that a 58 year old man will be in good Health until the child’s early adulthood than a 32 year old. There is a c.60% chance the 58 year old dad will live to the child’s 22 birthday.
I think a lot of people see a fit, healthy, well dressed and successful 60 Year old man and don’t think what the next 15-20 years will bring. I am not questioning their parenting skills or devotion, I am merely pointing out that parenting is a longterm commitment and their chances of being able to play an active for a long period of time are significantly narrower than parents of an average age. People in their sixties and seventies experience poorer health and higher mortality rates than people in their thirties and forties.
