If safety was the number one and solitary concern, I'd preferably dwell in the fresh, large intestines of a constipated cow living in 1567. For before man took it upon himself to journey into the unknown, and consequently reach his hand into uncharted territory, nothing would be going in or out of that safe haven.
Unfortunately, due to modern day practices, not even the tightest and smallest of holes can be truly closed off to the outside world – no matter how smelly the interior, might I add. Every step of technology is stalked closely by the advances of the underworld, which means very soon we'll not only have to deal with grave robbers but colon diggers as well. That said, it's absolutely foolish to question how safe we are in any environment.
Therefore, I hope to live in a gigantic mansion for years to come, and enjoy myself until naturally evolved burglars discover the fault to my 100& impenetrable walls, bypass my security cameras and infra-red laser systems to ultimately find me deep in slumber so they can shake me awake and successfully guarantee my death from the sheer shock and disappointment of being torn from a happy dream involving Jessica Alba.
Myesh, reality is sad indeed.
