I think there's some kind of general fascination with rich people ingrained naturally in the human mind. It's not just in comics. It's present in many fairy tales, mythology, religious books..
Iagree it can help the rich to get away with things. But I also think it's not fair to blame authors for using good old archetypes, while I also support kindhearted critique of those archetypes - it's important to understand their role in social context and to make authors aware of the downsides.
It's ok to eat a bit more nutritious food when it's cold - your natural body heating costs energy.
Cover your head when outside, your head loses an unreasonable amount of heat.
If your bed's too cold in the evening, buy a heating pad - a warm bed feels awsome.
If your hands get painfully cold, more excruciating pain may be waiting for you when they start to heat back up. To avoid the additional pain, put your hands under cold tap water first - I promise it's going to feel warm. Then increase the heat slowly until your hands are warm again.
