since he lives to be so old, hes got some dominant genes to remind you AD inheritance
in one hand he is holding a honey-comb to remind you of the honeycombed palmar PPK
on the back of the other hand he has a starfish to remind you of the starfish keratoses on the knuckles, feet, elbows and knees
since rip von winkle is so old, he has hearing aids in to remind you of sensorineural deafness (GJB2 gene, same as in KID)
around one of his fingers there is a rope tied so tightly that he cant get it off and that its fibrosing and amputating his finger= pseudoainhum (constriction bands that form around finger leading to amputation)
since hes older, imagine his skin is extremtly dry and ichtyotic to remind you of the generalized ichthyosis (loricrin gene)
- picture the loricrin lorax in the background (orange cartoon with mustache) to remind you of loricrin gene defect
