An insect bite stands out particularly in the memory of my wife and myself. On our 25th wedding anniversary we were playing golf at Burgenstock, on the edge of Lake Lucerne in Switzerland. Minutes after Carol scored her first ever birdie, holing a 40 foot putt on a short par-4 on the 9-hole course she was bitten on the ankle by a mosquito.Eight years later she still has traces of the scar, as the bite blew up to the size of a tennis ball and she was taking double penicilin for what seemed months.
