Chocolate and porridge are the secret to a long life, at least according to Rosanna Davison’s grandmother, Maeve, who has just turned 100.

Maeve was born on 22 June 1926 and lived through countless evolutions and advancements in her lifetime.

Her nearest and dearest were by her side as she marked the phenomenal milestone, including Rosanna, who penned a thoughtful tribute to her gran.
