Why it should be otherwise? It’s not like we’re sentient creatures, capable of influencing our own habits. We’re just mindless biological automatons, oblivious to the fact that we’re marching to our horrible, painful and IMMINENT demise. It’s not like I care about that either. Give me entertainment, give me food and comfort and I won’t give a duck about future. Why give an effort of thought to such amorphous things when I have so much to enjoy in the present? Clearly, that would be a fool’s errand, and I’m not a fool.
