I work three days a week in Switzerland, and while the hours are looking, I can cf a bit in the evening.

If I was at home, I'd be doing stuff with my wife and daughter.

It's looking likely that I'll be having to stay at home shortly, and that'll mean less cf.

To be honest I feel the danger (it is a danger for us, because my daughter had cystic fibrosis) is on the uk side, not the actual flight or being abroad. There are people using the trains when significantly sick, and there's a lack of soap / hand sanitizer in the station toilets. And it is crowded. Whereas in Switzerland you have lots of space in town, or in the office, and everywhere has hand sanitizer.
