Tubby the Labrador retriever loves to take walks. He also
loves to recycle. Every day. Tubby spends his time outside
looking for plastic bottles. He finds about six bottles a day-
sometimes more. Tubby crushes them in his mouth and
brings them to his owner, Sandra Gilmore. Then Sandra
puts the bottles in a recycling bin. Tubby lives in England.
He has been collecting bottles for six years. So far, he has
helped recycle 26,000 bottles. Tubby holds the Guinness
World Record for most bottles recycled by a dog. Good
boy!

recent brain research has shown some surprising benefits as a result of formal musical training. learning to play a musical instrument appears to develop parts of the brain that can even influence academic results. the studies indicate that the earlier a child begins training, the more benefits there are. one such study showed that children who began musical studies before the age of seven had a more developed brain in the region where language production and auditory processing take place. scientists believe there is mounting evidence to show that early musical training can improve brain function.
