Neighbor's mom is 81yro.

She took her mom to nearby coffeeshop to eat breakfast.
Unfortunately she had to go to the toilet.  She told her mom to wait for her.

When she came out her mom had "disappeared". Coffeeshop people said her mom had walked out. Thinking her mom was still nearby she quick walk around the block to find. She couldn't and contacted my mom. My mom asked me to help.

To cover the area quickly I took my bike to cycle around there are so many blocks, fields and areas. 

After combing around for 1 hour j found the old lady sitting at a bench looking at the play ground swing.

I went up to her she struggle but manage to recall my name.

Neighbor came to pick her up and send her home. 

She told me her mom's dementia has been getting worse and she would wonder off. 

Often she is quickly found. But this time she managed to walk quite a distance to place that was hard to find.

I was thinking how to solve this type of problem as our population age and often we hear of elderly getting lost. They can be quite terrified by their situation.

One way is to implement "air tag" for the elderly so they can be found quickly. 

The cost is quite low.
