For the second leg of their European health adventure middle aged mates Paddy McGuiness and Chris Harris touch down on the rocky Greek island of Ikaria, nicknamed the island of longevity. One in three Ikarians live well into their 90's, ten years more than most people in the UK and Paddy and Chris are on a mission to find out how.In the Highland Plateau they meet a typical Ikarian family who embody the simple way of life and are set to work earning their self-sufficiency stripes, with Chris milking goats and Paddy set to work putting up fences. In the South of the Island they go fishing with Stavros, a 75-year-old fisherman who has no plans to ever retire.When it comes to de-stressing the island has it all – including surf. Novice surfers Chris and Paddy hit the waves for a stress busting surfing session that's more wipe out than Hawaii 5 0. Having de-stressed the lads have a night out Ikarian style – much to Paddy's disappointment is less Bacardi Breezers and more Backgammon. Playing board games like Backgammon are thought to keep the brain healthier for longer. Chris tries to teach Paddy but his patience wears thin and he takes on the locals instead…For their penultimate day on the island Paddy has a challenge up his sleeve designed to test their mettle, get them out of their comfort zone and build their mental resilience. Rock climbing! With a fear of heights is this a challenge too far for Chris.On their final day on the island sees Chris and Paddy head to the hills on scooters and join one of the island's famous village parties – a Panigiri. After a feast and being welcomed by the locals, Paddy decides to give something back with a game from home – Bingo. Luckily he doesn't travel anywhere without his bingo balls…
