Beyond the obvious—how can sharing a dessert like this not perk you up?!—there are good reasons to bake your lover a pumpkin pie or order a slice of it instead of another cocktail.

Eating it can sometimes feel a little like swooning, due to phenylethylamine (a stimulant related to amphetamine) and tryptophan (a building block of serotonin, a brain chemical involved in sexual arousal)—compounds that are released in the brain when people fall in love.
