The media attention on Angela Merkel's health. Is it anyone's business?

German Chancellor Angela Merkel has been in the media spotlight recently because she has been seen on camera shaking for a third time in a month. Video footage shows Mrs Merkel trembling, shaking back and forth alongside Finland's prime minister during a ceremony in Berlin on Wednesday. After the incident, Mrs Merkel said she was "very well" and there was "no need to worry". A recent editorial in German newspaper Bild has said that "the health of Angela Merkel is now a political issue." But should it be a political issue? Vinny got the views of commentators Fionola Meredith and Patricia MacBride, and medical ethics expert Dr Brendan McCarthy.
