Mark kravetz, 88, from North Finchley, has lived by himself since he was widowed 20 years ago.
Health problems have meant he cannot get around as much as he used to, and he suffers feelings of loneliness as a result.
"I've always been a sociable guy. but my health got worse - I've got emphysema and I can't walk far - and now I feel very isolated," he said.
