Puberty

Do you remember what age you started Puberty? Are kids hitting puberty earlier than their parents? Do kids develop quicker now adays? I have four of them that are right about that age, at least that's what everyone keeps saying. I don't remember puberty being so soon...............do you?? What is the average age now? Things are so different now than when we were kids, each day my kids show me how different things are.
