Dad lives in sheltered accommodation.moderation and I go round daily and take him out most days but he still goes out on his own when I cannot be there. He is 80 and his under 9 stone now with all his walking he does. Before I got there today he had gone off for a walk. He has a tracker but it we t flat an hour into his walk. Has it seemed to be his usual route I left him as he is usually back at lunchtime. Anyway 3 hours later he had still not returned so I went out in the car to look for him. After another 2 hours touring around his usual routes I called the police. They were excellent, checked the curb at the shop he goes to on his walk and were about to send the helicopter out when almost after 7 hours he walked in wondering what all the bother was about. He could not tell the policeman where he had actually been other than further along the road and in the fields. He did tell him all about his national service nd his family (not me his daughter) his brothers and sisters. He was in a jolly mood after this marathon walk. The tracker is new and I have had to change the batteries daily where the previous one lasted about a week so need to get it sorted. I do not know how he keeps going.
