I am a lot older than you and currently on holiday in Australia!!! During my stay here I have flown from Western Australia to the East Coast, and back again, and had a trip to Bali, wonderful Country, will definitely go back. I am going home to the UK next week, have a cruise booked to the Med in September, a tour of Portugal early next year, before returning down under for a couple of months!!! Go for it whilst you can, I am lucky to enjoy perfect health but am very aware that, at my advanced age, that can change at any time, so making the most of it xxxx good luck and happy travels xxx
