Stoobalou writes with this excerpt from Thinq.co.uk: "A new study has shown that brain training games do little to exercise the grey matter.

John and Ann Till, from Petersfield, in Hampshire, spent three months collecting recyclables to pay for their honeymoon flights. The couple earned one reward point, which they converted into BA air miles, for every four items they recycled. In the end, they amassed 36,000 miles. Mr Till, 31, a railways communications manager, said, "We wanted to make our honeymoon special and were trying to think of ways to raise money for it. I saw on the machine that you got a Tesco Clubcard point for every four items you put in. For every 250 points you got 600 British Airways miles. We worked out that it would be possible to turn rubbish into our flights — as long as we had enough."
