well in that case not all 40 yrs old are single either ;) ............bt honestly u guys r making 40 to look ancient which it def is not. yes some people just give up on theirself bt they can do that at any age...just luk at some 30 yrs old and they wl luk like they r already havin a mid life crisis.
because it is they don't have that much energy to cope with it.
those 30yr olds who have a huge belly will be the same at 40 =P
I am not really asking about their behavior and work patterns,whether they are boring or fun. I am asking are there any biological discrepancies associated as is thought to be with women over 35?
Yes there are studies that show that there is an increased risk of genetic issues to children born to men over 40, and the risk further increases with age.
I know a few guys who got married around 33-34 and the girls were 25ish...and their marriages are going well alhamdullilah. However everyone has their own preference. I dont think I would personally want more than a 5years gap
