@TheEternalAnglo @InvictusManeo @Honkers This is the result of 200 years (16 generations) of inbreeding was Charles the II of Spain.

At age 4 he could barely walk and was still breastfeeding. At age 9 he couldn't read or write. He was completely bald at age 29, died at age 38 and his death led to the War of the Spanish Succession, killing between 400,000 and 700,000.
