Aubrey de Grey is mostly known for spearheading radical life extension technologies with SENS, beer consumption and his distinctive wizardly beard.
Is senescence modelling and beardedness inherently related? Science has not yet answered this question and perhaps never will. Even the book Death is Wrong doesn't yet have the answers.
Aubrey says he has the beard because his wife likes it.
