Forget the John Lewis Christmas ad – people have been in floods of tears watching a heart-breaking German Christmas ad about an old man’s bond with his granddaughter. The two-minute commercial shows a grandfather who, isolated by the coronavirus pandemic, starts his own solo fitness quest with just a single kettlebell. When he finally meets with his family at Christmas, he’s now strong enough to be able to pick up his granddaughter and lift her up to put the star on top of the Christmas tree. The ad, from German pharmacy company Doc Morris, has gone viral online with people saying it “broke their heart open” and has won admiration everywhere after some heavyweight media coverage.
