He spends a lot of time with them.
Following his friends' wish, there are recent pictures of the children here:
He likes to hike, bike, listen to music, play golf and read fiction.
He speaks French, German, English, Russian and Swedish, and likes to read also in Latin and ancient Greek.
"Nel mezzo del cammin di nostra vita
mi ritrovai per una selva oscura,
ché la diritta via era smarrita.
Ahi quanto a dir qual era è cosa dura
esta selva selvaggia e aspra e forte
que nel pensier rinova la paura!"
He likes tasty wines and food. (As to the food, he also likes to prepare - like a good chemist would.)
He is still thinking about what else to write here...
