Expand "kinds of activities"

[marcoscaceres]

I might be good to expand the kinds of activities to include people that are:

• traveling across borders
• on guest account on another computer
• on a shared device - particularly, where there may be power imbalance: parent/child, spouse control, familial control where a patriarch or matriarch may control access to the device.
• the user transitions in either age (child to adult), gender, sexual orientation, etc.
