Tableitis

The disease was first commonly found in the mid 17th century, With sugar plantations across the globe and monetary currencies being shipped from one side map to the other there were many pirates fighting each other for the prize while starving at the same time. Their limbs were slowly lost and reverting to a more natural solid wooden state.

The disease can be stopped if caught in time but if you ignore the symptoms eventually all four limbs will become wooden and your body will have fully converted into an antique wooden table. The remains of these long lost sea travelers can be found in antique shops and more commonly on TV on GPTV's Antiques Road Show - Tables Table Tables.
