SENIOR MOMENT - about 4 units of an inexpensive but dryish fizz: 1 Cointreau: 1 fresh lemon juice (+ some of the rind). Cointreau and lemon juice in first, pour fizz on top, garnish with lemon rind. Remember that the fizz should be well chilled. The senior moments arrive after about three glasses.
OLD AND BOLD - 1 of Drambuie: 1 of vodka (or gin if preferred): 1 of fresh lime juice: 1 of fresh orange juice (and some of its zest as garnish). Shake (a la James Bond) with ice, keeping back the orange zest as garnish. After 2 glasses you get the Bold, after about six definitely old!
