Does this mean that women have been checking out the size of men’s fingers and thumbs and giggling about size for millions of years?
Perhaps that almost universal female reaction across cultures is another inheirited gene trait.
And our ancestors who developed the opposable thumb were no doubt the sexy Fabio boy toys of their time.
A nurse I used to work with said that she learned the finger/hand method of figuring out the size of catheter to use, that it works every time. :’)
