If Vulcans were really logical wouldn't they let out their emotions so they didn't get that disease at old age

Answer 1

Excellent point! I agree completely, and at the risk of appearing to be a complete nerd... would remind you that there have "historically" been many groups of Vulcans who have rebelled against the teachings of Surak and embraced emotion, though most apparently ended disasterously.

I've also noticed that the focus on logic in Vulcan culture may not be as ancient as we've been led to believe. For instance, Commander T'Pol (First Officer of the NX-01 Enterprise) exhibited emotion regularly, though she denied it vehemently as did many other Vulcans of her time. It was many years later when emotion seems to have become more well controled, as evidenced by Tuvok and of course, by Spock (who was of course a hybrid).

So my point is that perhaps they haven't worked through the problem long enough to see the logic of your idea. You might write to the Vulcan Science Directorate as I'm certain that they have sponsored much research on Bendii Syndrome that might include discussion of this idea.

Live long and prosper.

Answer 2

Vulcans control their emotions, they don't "keep them in". That disease causes the loss of mental control over their minds and bodies.
