How we change what others think, feel, believe and do
This is based on the ‘Selfish Gene’ principle that we are simply ‘gene machines’, programmed to propagate our genes as far as we can. Natural selection (as per Darwin) ensures that the unsuccessful people do not get to spread their genes.
This affects how we view other people when choosing a mate. Men will look for women who look like they can bear their child. They thus look for young women with large breasts, good-sized buttocks and general health and fitness (such as toned and reasonably slim body). Women will look for strong and powerful men who can feed and defend the family (age is less important).
It also explains why men tend to be polygamous, seeking to spread their seed as far as possible, whilst women seek a secure family unit as they need long-term stability to bring up the children.
Notice your own reaction to people of the opposite sex. Who do you find physically attractive? Why?
If you are a woman, ensure you look good. If you are a man, look powerful. This is only, of course if you are seeking to attract the opposite sex.
Beauty is only skin deep. Look beyond the physical signs.
