Where are they now (do you think)?

As a fun thought experiment, with it being just over 10 years since the series finished I was thinking about where the main characters might be now. Mark and Jez would be in their 50s.
Did Jez ever move out?
Has Mark found happiness with someone he likes or settled into misery with Soph?
How is young Ian doing as he enters teenage?
Did Hans get the Macedonian moped rental going?

Any other thoughts?
