My father was a brilliant child who finished all schools with highest honors. He became a scientist, theoretical physicist, and later worked as a professor of physics, taught scientific worldview, and published a couple of books on narrower subjects (like solid-state physics) and articles (methodology, etc.).
He swam really well and played volleyball. He read a lot, and collected a huge library of good books: mathematics, science, philosophy, and classical literature.
He wore formal suits with pastel mono-color shirts, trench coats, and elegant hats (Fedoras). He used taxi for transportation. He did not have any bad habits, drunk very little alcohol, was a good swimmer. He loved strong coffee (Turkish style espresso), cigarettes, and food - and I don't really know what and whom else.
