This is true but its also true that we need oxygen to survive.. you don't need Test to live. In fact, the Y chromosome is literally the only chromosome in the body you can delete and you'd still be alive (though we couldn't reproduce without it). Without all the other ones we'd die.In that case oxygen is poison. Much more than anything else you've put un your body.bwithbevery breath you take, byproducts from oxygen used by your body are released in the form of free radicals that age and eventually kill you like nothing else. Also it somewhat conspicuous that the only people claiming this are people that battle hair loss.
