i remember reading about some study where two groups of people went round a museum. One group were told to photograph everything that interested them with their phones. The other group weren't allowed to take their phones in with them. Afterwards they filled out a questionnaire and the phone group remembered far less than the non-phone group. the slant of the piece was that the brain doesn't bother passing things into memory if it knows you're capturing stuff extermanlly, the bain is hard wired to find energy efficiencies...
Also selfies. Forget yourself.
