Is heavy metal something that has to be sucked with mothers milk?

I found myself in this position few times. I’m going back to Poland, the place I was born, place where my mother lives. When I’m back home I’m always listening my music. BLS, Sepultura. Machine Head, AD/CD (true, old), Pantera (true, they’re dead, most of them), Metallica, Soulfly, Opeth, In Flames, Dimmu Borgir, Thyrfing,… She is 60 years old but she always enjoys it. My question is: is heavy metal something that has to be sucked with mothers milk?

BTW: Did you noticed that Zakk Wylde in “Forever Down, Mafia” sounds little bit like Ozzy?
