I didn't ask that .

Never mind, I enjoyed it and thought it made an interesting read.

But back to your question on Paternal Age at conception etc for a moment.   I fear you might be seeking itemized info which simply doesn't exist (yet).

Nevertheless, I sharpened my shovel and, undeterred, dug some more.  I did find one website that discusses your required themes - ie the risks involved with conception by fathers in later life.

It is the US National Library for Medicine's website... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3854059/

Maybe give it a try, Cosmos?  Among other things, it says that while the median age for paternal conception in the US is 27, the most frequently used cutoff is 40 - But (and here's the crunch) "...paternal information is often missing from the birth certificate and the age of the father is not even reported in 14% of all births."

"So there currently exists a need for improved data collection, guidelines and outcome research based for Advanced Paternal Age."

Dr. Wyrobek, a senior staff scientist at the Lawrence Berkeley National Laboratory, said that an immense amount of work still remained to be done. 

"There are more than 30,000 genes and we've only measured the effects (of advancing paternal age) on ...two of them in sperm," he said. "Many gene mutations in sperm can cause genetic diseases in children, and these still need to be measured in older men, but we don't have the tools yet."

That probably goes a long way to explaining why I couldn't find any specific websites dealing with the father's increasing age at conception and the increasing risks of Alzheimer's in the infant in later life.

Maybe there will be more info in ten years time when the measuring tools will be in place?

There's increasing evidence that older fathers may be the root cause of Alzheimers disease . Are there statistics kept about fathers' age at time of (physical) conception?

Sorry Cosmos but I can't find any source of statistics showing father's age at conception being important...but I did find find this National Public Radio site in the USA.  It says that there are many other more important factors that shape a child's mind than the father's age...and it discusses them a bit.  So relax, Cosmos.  No matter how old your pappy was, you probably have nothing to worry about!  Probably.  wve
