PHRASES such as sea-change and tree-change have swiftly become part of our contemporary vernacular. Such shifts can be permanent or part-time and could involve life-changing holidays or moves far afield. Many of those who embark on such adventures pen tales to encourage others, which is the case with Growing Old Outrageously by Hilary Linstead and Elisabeth Davies (Allen & Unwin, $29.99). These former school chums of a certain age reunite after 35 years and soon take off on a series of grand gallivants. It’s reaffirming stuff and so, too, is Retire and Live the Dream by Annette Edis (A&A, $29.95), in which the author and her husband, Ray, move to Italy for a well-earned slice of la dolce vita, but not without myriad challenges. The message is clear, however — it’s never too late to up sticks and start anew.
