Where do they find these interviewers??!!
Why does society (I'm being a bit sweeping there I know!) think that, as soon as you hit 60 you become a brain-dead imcompetent?
We bought my 85 year old mother a mobile phone because she was so deaf that using a phone to speak was a nightmare. I taught her how to text and that's how friends and family communicated with her. After she died aged 89, the comment that was made by her wonderful carers in the residential home in which she spent her final few weeks was, "We really miss hearing the beeps of a text message coming on to Peggy's phone!"
She also used to go to the local library to use the computer to email her sister in the US. She was in her late 80s.
Her sister in the US was still driving from Florida to Rhode Island and back, on her own, once every year when she was in her 80s. My geography's not good, but even I know that's a very long journey! She was also very computer literate and regularly emailed right into her 90s.
It's astonishing that there seems to be this prevailing attitude that the over 50s are to be marvelled at if they can still operate a kettle or change a lightbulb!
