Quote - Wigs were often worn over short cut hair. Age and weight have a lot to do with such things too.

True - doing so kept the lice to a minimum, because you could always get a new wig. Also, long hair is harder to keep clean when you bathe as infrequently as they did back then. Me, I think it's kinda cool - it puts a human face on him. IMHO, the expression is merely neutral. They did one (speculative, due to there being no skull) of Jesus awhile back, based on what were common DNA-based characteristics and social mores of that region during that period. It was pretty cool, and shattered the typical "tall blue-eyed white guy with long beard and flowing long hair" image entirely. This one of Bach wasn't nearly so surprising. Looks like an average guy for the area. /P
