Sleeve Length

I had a conversation today with a friend about optimal T-shirt sleeve length.  I argued that sleeves should go all the way down to the start of the forearm, in order to provide sufficient coverage even when stretching or reaching.  I detest long-sleeve shirts in the same way claustrophobic people hate MRI's, and as such I haven't worn a long-sleeve shirt for five years (jackets excluded).  My friend doesn't mind them, and somehow manages to bear the painful cutoff of circulation provided when you roll up the sleeves.  Although the conversation concluded without much resolve, it did prompt me to illustrate a guide to sleeve lengths.  In my opinion, the orange-colored sleeve length is the only wearable one - all the others are simply inferior.
