A daily reading practice for you for today! Today's grandparents are joining their grandchildren on social media, but the different generations' online habits couldn't be more different. In the UK the over-55s are joining Facebook in increasing numbers, meaning that they will soon be the site's second biggest user group, with 3.5 million users aged 55–64 and 2.9 million over-65s. Sheila, aged 59, says, 'I joined to see what my grandchildren are doing, as my daughter posts videos and photos of them. It's a much better way to see what they're doing than waiting for letters and photos in the post. That's how we did it when I was a child, but I think I'm lucky I get to see so much more of their lives than my grandparents did.' Ironically, Sheila's grandchildren are less likely to use Facebook themselves. Children under 17 in the UK are leaving the site – only 2.2 million users are under 17 – but they're not going far from their smartphones. Chloe, aged 15, even sleeps with her phone. 'It's my alarm clock so I have to,' she says. 'I look at it before I go to sleep and as soon as I wake up.'
