Alright, I'm just going to ask it. We've seen Kirk with his shirt off dozens of times, and he never has any body hair. Fair enough, it makes him seem sleek and well-groomed. But why didn't they make Nimoy shave his chest too during the rare glimpses we get? It even seems antagonistic to the character - given that Vulcan is an extremely hot planet compared to human standards, yet Spock is comfortable at room temperature, why does his species even need body hair? And if it comes from his human half, wouldn't he shave it out of embarrassment?
