@sozobe,
I'd say he, like many many people, married too early relative to his maturation, if you go with the vow fulfilling mode of marriage over time. Vows may vary, and that's another subject.
I think it is hard to grow up in public.
On interest in all this, as posited by Mame and others - I've followed Tiger with some moderate interest over the years. I like sports, and weaned myself into life as an isolated early teen reading sports stories of the year, not because I collected baseball data, but because I was interested in what I would later think of as the sociology (psychology? what?) of sport, plus those were the books at hand at the local library. Reading is how I learned about life around me in my first batch of years, and I still learn from stories in a lot of places, including the sports pages.
