My calves are like rocks! And while that's a good thing I guess, I've taken a day off from exercise. Don't worry - I'll be back at it tomorrow plus doing loads of walking in Basel over the weekend.
BTW, if my father is reading this - that client of yours would have been from the Kingdom of Mustang (pronounce MooSTANG) which also looks like a great place to visit in Nepal. Apparently they only get about 3000 trekkers per year at the moment and only opened up to the outside fairly recently. The key is to go soon before the transport links improve and the culture is sullied.
