Are we supposed to took like cavemen?

We're created with a face that grows beard, and we're created with scalp that grow hair too, so really why don't we look like how we supposed too? Like cavemen! If we look at all the records we have about people in the past like pictures or paintings we don't see anyone looking like druids or cavemen long before cisors and shavers were invented and if we don't cut our hair or shave that's how we're going to look like.
What about our teeth? Mother nature gave us teeth but if we don't take care of them they are all gone by the time we reach 30, why are we what we're today? A weak homosapian with iphones and laptops, now thats pathetic, i wish i was born hundred years ago, they didn't call it la belle époque for nothing none of any technology today but happiness every where. Have we been cursed by god because of Adam? English is my second language so please excuse my bad writing.

Life expectancy in the days of the caveman was only 30 years. Be thankful you live in a time of medicine and good hygiene.
