The bulk update request #11201 is pending approval.

create alias nervous_grin (286) -> nervous_smile (4967)
create implication nervous_smile (4967) -> nervous (25219)
create implication nervous_sweat (3952) -> nervous (25219) # duplicate of implication #67502

Reason: A grin is a slight smile, so it may as well be a smile.

Also nervous sweat doesn't imply nervous yet. If you disagree provide at least one counterexample of nervous sweat or nervous smile where the character in the nervous sweat/with the nervous smile isn't nervous.
