Another Dumb Idea From Google

Ya know. I can't speak for everyone but can tell you that on at least one occassion I wasn't in the right state of mind while sending a later found to be damaging email. I disagree with your comment and think just the reverse. I feel this feature is actually brilliant and am glad to see that people are actually trying to improve even seemingly basic offerings like email. I think this shows that Google is trying to improve the user experience.
But, I haven't seen the math questions. If they want you to calculate the square root of a polynomial or something crazy, then the feature probably isn't a good solution. If the question is 2+3 or 5+5 or even 6/1, I might accept it.
Being a man, I think we often act before thinking and this may just help us out a bit. Obviously all women are perfect and this feature may not make sense :).
