SOUTHERN Health nurse Karen Johnson may well be feeling light-headed after losing her locks for World’s Greatest Shave. The nursing unit manager’s children, Robyn, 13 and Jill, 15, gleefully took charge of the shavers on March 4 to shave their mum’s head. Ms Johnson will donate all the money she raised to the Leukemia Foundation, which supports patients and families living with leukaemias, lymphomas, myeloma and related blood disorders.
