Depends on how hard performing tasks are. Can I punch trees to get wood, it doesnβt hurt like hell and doesnβt break my fists? Can I dig through the earth quickly with just my bare hands? Can I construct a dwelling relatively easily? If yes, then I think Iβd be ok after getting over the initial shock of βWTF?β
If weβre talking real world physics, then Iβm probably dead the first night.
