If the MAFIA was after you and you had a choice of either going on an expedition to the Antarctica to participate in the building of a secret research facility for a Swedish government project for 5 years or get a new identity from the government and move to Guatemala to become a gardener in the house of a famous soup opera actress, which option would you chose?
On the practical side. Antartica is much safer. You really have to have permission to stay at one of the research facilities. I think Mafia hitmen would stand out in Antartica. Might blend easily in Guatemala.
Of course the Gardner will have sex with the soap star in the garden. This has to be a tropical garden right so it will be hot and steamy sex, right before the hit man finds and dispenses with the both of them.
