Gentic inheirtance could be the thing though as well.
Some genetic problems can actually skip generation. They remain dormant in a child, who's Father had the problem, and who's future children become "active" to the genetic anomelie.
Someone could have a Father with Alzheimers, not get it themselves, and then have one of their children get it, around approximately when they become 65-70 maybe older. Potentially the exact same age as the Grandfather did as well.
I can't recall the reasoning for this though, or why this inherited trait can be dormant, but triggered in future generations, or what are or is the trigger(s)
Think of a trait being displayed phenotypically... Since you only inherit about 25% of a parents genes, you are not guarunteed to display a phenotype that makes you alike unless the traits are simple recessive or dominant genes. The genetic code you inherit is so unique you might have two children in 128 billion (from same parents) who are identical-- at least thats what I remember from my developmental stats last year, numbers could be off. Just because one parent displays it doesnt mean you WILL inherit it, there are many possible outcomes.
I hear saw palmetto works too... but eating well (the food advice given earlier is great).. also vitA reduces sebum production, which is what I believe contains the DHT that harms your hair follicles.. Just dont OD on it!
