Mikako 72-sai

Mikako, 72, has just lost her husband. From now on, she plans to live alone, sticking with the house where she lived with her husband. When her worried children and grandchildren give her a smartphone, she accidentally connects it to her dead husband's account... If you read this, old age won't seem so bad. The art of living alone near age 100 (lifehack)!
