Is he of Indo decent cause he looks a bit Euro looking tbh than Arab but his paternal ancestors could be Lebanese or Syrian
I hope you do realize that half of Europe is genetically and ancestrally the off-spring of people native to the Arab world (Neolithic farmers) who colonized all of Europe. What makes Northern and Western Europe genetically distinctive from us Arabs is the native European Paleolithic ancestry (haplogroup I) and fairly recent (4000-3000 years ago) steppe invasions from what is the Russian steppe today.
Racially both Arabs and Europeans are Caucasian people. There is no difference expect for complexion and certain more and less predominating features and that depending on where in Europe. We are not talking about the racial difference of a Congolese or Chinese here but geographically and genetically related/closely related people.
99.99% of the Arabs in Indonesia (some 5 million people largest non-native ethnic group in Indonesia - even larger than the Chinese diaspora) are originally from Arabia, mainly Eastern Arabia, Hijaz and Yemen.
Looks pretty Arab to me, just a reddish complexion, which is not unknown in the Arab world, Arabia included, even found among isolated Bedouins.

Similarly there is a large naturalized community of people of Indonesian and South East Asian origin in KSA (Hijaz mostly) who have been living in KSA for generations.
Whenever Arabs and South East Asians intermarry, the offspring is often an lookalike of the Arab part in the relationship or the South Asian part. Although the mixtures (where you can see both racial influences) tend to be very exotic looking and beautiful if you ask me.
I think around 45-47...your child becomes 18 when you are 65...(the age when you start declining in physical cognitive powers)
Males can in theory create offspring as long and from the exact time that their equipment is working/starts working. It all depends on the female. Males (at least in the Arab world) who decide to have offspring in an advanced age (60 + years) with their second, third, fourth wife or relationship, often have a large family already with numerous siblings. So even if the father passes away at an early age (from the perspective of his youngest offspring) that offspring will be surrounded by a large family, many siblings, nieces and nephews in every age group and a fairly young (in comparison for sure) mother. In fact an uncle, older male sibling etc. often takes a role of the father if the advanced aged father passes away.
Ideal age is 25-35. Earlier as well, it depends on your maturity and life situation but it makes little sense to put a number or limit as every situation/relationship is unique.
The question of time is more a thing that females have to worry about, which they do greatly. There is a much greater taboo (in every culture that I know of) of a lone women that have not given birth, than the opposite case.
