Silly girls

In the future there will be girls with huge muscle feet. the ones who can't walk proper in high heels will make children who have big compensatory feet muscles. they also get small arms and their arms are always at an angle to keep their balance. also their necks will be really short because they were afraid of falling over. and they will have big calloused hands because the ones who fall over all the time because they can't walk in their shoes, develop extra thick hand skin to protect them and it gets passed down to their new silly-children. and they are all happy. they marry nice people
