The Check-Up: Finger Length Linked to Health Problems

Now scientists might know why, genetically speaking

Have you looked at your hands lately? Like, really, really looked at them? Scientists in Florida have been studying hands to figure out why finger length has been linked to everything from sperm counts to breast cancer. Their latest discovery reveals that it has something to do with sex hormones present in embryonic development—that hormone levels determine finger length and proportion.

Let’s play this one out: Now that they understand what determines finger length, maybe they could eventually control predispositions to certain diseases—you know, if they can learn how to manipulate or control the hormones. Of course, such genetic engineering is a long way off (and bioethicists might question whether it’s even right to go down the road), but it makes sense right?
