EDIT: I'm not saying that 'modern' stressors aren't actually stressful. I'm saying that not knowing when and where your next meal is coming from or if you're surviving the winter is just as stressful.
It’s not as simple as that. I’ve been hungry and cold (poor, homeless or near enough to it). I’m well off now. I stress about other things than hunger and temperature: but that stress is very real, and just as urgently felt.
