One man from Wales is proving that age really is just a number.
Introducing Trevor Ward, the 104 year-old putting us all to shame as he treks the hills and countryside almost every day near his home in Clydach Vale.
The former miner said the daily walks keep him feeling young.
Trevor meets his friend Mervin, who is 83, to walk the hillside each day.
He says fresh air and walking are the secrets to staying healthy.
But he still makes time to go dancing and to the bingo.
You can see more about Trevor on Coast and Country tonight at 8pm on ITV Cymru Wales.
