Jack Potter with his diary of his 70 years of marriage to Phyllis. An elderly husband who has documented more than 70 years of happy times with his dementia wife in a diary now reads their stories to her to jog her memory. Jack Potter, 91, first wrote in his diary after meeting Phyllis, 93, at a dance in Strood, Kent, in 1941. Lovestruck Jack said he rushed home, aged 19, on the evening of October 4 and wrote in his journal: "Very nice evening. Danced with [a] very nice girl. Hope I meet her again." Since that date old romantic Jack has kept every keepsake in his diary, noting down of every dinner, holiday and conversation the couple have shared.
