Got a "Big O" birthday coming up? Go on, treat yourself to a travel adventure.
On my 40th birthday, I climbed Mount Kilimanjaro, the highest peak in Africa. Any despair I might have felt about becoming irrefutably middle-aged was completely overshadowed by the sheer exhilaration of reaching the crater edge, watching dawn rise over the vast plains below, then striding across the snow to the summit.
But then I've always tried to be somewhere special on my birthdays, particularly ones containing a "Big O".
A hot-air balloon ride over Bagan during sunrise is hard to beat when welcoming a new decade.
For my 30th, a friend and I raced each other down the Hahnenkamm course at Kitzbuhel, which was a bit more exciting than my 20th, spent in London's West End watching Agatha Christie's The Mousetrap.
The point is that, especially on our birthdays, we're all unique individuals who like to celebrate in different ways. So can there really ever be an answer to the question: "Where's the best place in the world to spend your 50th?"
Yet that was the brief: recommend destinations for someone about to pass one of the Big O Birthdays, from 20 through to 80.
Obviously I had to consult a few friendly experts. Here's the best of their inside info:
