We visit my grandmother in Sweden every year and this time my husband can’t make it. It’s just me and her, but this year she won’t be doing our traditional icy dip and sauna. Down at the lake I meet Lars and Johan, two strapping Swedes who share my tradition. Listen as things get naughty in the sauna after our cold dunk as I take the both of them at once in places no-one has ever been before!
