People watch their own photos so much over Facebook. They like seeing them from 3rd person perspective and truly enjoy the person behind the happy moments and empathise with the sad moments. There is another term for it, living the memories.
It will be truly amazing if they can start visualizing before living the moments. See them doing things from a 3rd person perspective and do and achieve living every moment to its best from 1st person perspective. This is a great way to live. This enables living in the moment. This is called living the dream.
