Despite having family in his early years, he had no surviving relatives as of his 105th birthday. That is why the Royal British Legion reached out to Twitter. They wanted people to know why and how they could do something for Ernest.

According to Yahoo! News, the membership engagement manager for the Royal British Legion, Rachel Venables said: "The Second World War generation is inevitably diminishing, but occasions like this are an opportunity for the RBL to remind everyone that their service and sacrifice means something and will never be forgotten."

Horsfall was ecstatic when he received so many cards. According to Yahoo! News, his girlfriend even visited from Iceland so she could spend the special day by his side.

If you want to live a long life, Horsfall says you should be "living as happy as you can" and keep a straight mind.
