So what is the bottom line why you don´t want anybody to remember you or what you look like? What do you fear would happen if someone remember and recognise you? If it´s not fear of someone stealing your stuff.

Because the way I dress and carry a front pack on my breast I stand out like a sore thumb and I don´t care one bit about it.
It might be my age (57) that makes me not give a flying hoot what others think of me.
