Physical chemistry insn't a must. Grow up. It's like saying you don't want to eat your vegggies and eat chocolate all day because veggies taste nasty. It's like saying you'd rather be obese because watching calories is hArd. Grow up. Eating your veggies is hard, but you have to do it because it's healthy for you, and simply saying they taste bad is such a rationalization. Likewise, if a man or woman is pefect for you in every except their looks, you should look past it because it's beneficial being with someone you actually love. Physical chemistry is not a must, it's just a social norm you've been brainwashed into believing. Again, it's no different than a drunk thinking he needs alcohol every day. Furthermore, physical chemistry inherently ends because both of ou will get old and look like shit. Oh, look, no more physical chemistry and 50 years in, gotta get a divorce! Grow up. Everything in life is about compromise.
