Travel Travel ignites that youthful spark, says Aisling Grimley, founder of the My Second Spring (mysecondspring.ie) website, which provides information and suggestions for those who want to stay youthful.And it doesn't necessarily have to be a trip to Machu Picchu. Take a bus or train to a different part of your county and go for a walk at a local beauty spot with a friend."Being in different surroundings can give you a whole new perspective on life," says Grimley.And, of course, international travel is very exciting too: "I heard of an 89-year-old woman who recently fulfilled a lifelong ambition to visit Ethiopia. She didn't want to rely on other people's availability so she joined a travel group and headed off."Take photos and re-live the adventures when you get home - then start to plan your next trip.
