If I am teletransported to another planet, as for example Parfit proposes, do I take then my social identity with me or only my personal identity? Can we say that Haile Gebrselassie is the world record holder on the marathon on a planet where the gravitiation is only 10% of what it is on earth and where it is impossible to run a marathon?
And what if I switch bodies, an example also often used in the personal identity discussion in the analytical philosophy of action, (for example by Williams) ? Do I get then the social identity belonging to the other body or do I keep my original social identity? Is Haile Gebrselassie still the world record holder on the marathon if he switches body with Paul Tergat? Who is then the real world record holder: the person with the mind of Haile Gebrselassie or the person with the body of Haile Gebrselassie? Who is then the real Gebrselassie, who is then the real Tergat?
