Tell that to 50 year old Dame Dash and his new born son Dusko
What I said is supported by research. I know of an older man that impregnated a younger woman and their son came out with autism, juvenile diabetes, sickle cell anemia, etc. The wife also had gestational diabetes. There has been research linking older sperm cells to autism, premature birth, gestational diabetes, low birth weight, schizophrenia, babies being in NICU, fetal mortality, etc. The older you get, your cells go through oxidative stress. Same way a woman takes a chance of having a child with complications as she gets older, a man takes a chance as well. We are all playing probability game. It may work in your favor or it may not.
Keri is not too old for marriage. She can always adopt. She could have frozen her eggs and can pay someone to have the baby for her. She can also marry someone that do not want a child or already have kids.
