But people do not have the same chemistry. Some people tan easier than
others.
Some are more verbal; some are naturally thinner or fatter; some learn
and talk
faster; some like foods that others can't or won't tolerate; some are
more considerate
than others; some tolerate pair more than others etc etc etc etc
