Telegraph – Children ‘getting weaker because they don’t climb trees’

Dr Sandercock said: “This is probably due to changes in activity patterns among English 10-year-olds, such as taking part in fewer activities like rope-climbing in PE and tree-climbing for fun.”

“Typically, these activities boosted children’s strength, making them able to lift and hold their own body weight.”

The fact that 10 per cent could not do the wall bars test and another 10 per cent refused to try was “really shocking”, he said.

“That probably shows that climbing and holding their own weight was something they hadn’t done before.”

Crazy.
