I have many of my husbands OS maps on a shelf in the bookcase. My husband, 57 years old is in 24 hr care with Early Onset Alzheimers and Frontotemporal Dementia. We can no longer walk together sill share his old maps for reminiscing. I intend to challenge many walks and when possible raise money for any of the Dementia charities. Alzeimer's is the first charity of my choice as they helped us through a very difficult, lonely journey of three years while we had no diagnosis of the mystery illness thought only to be effecting those more elderly.
