Age computation

As suggested by Number One in the first pilot episode of Star Trek, age computation can sometimes be interesting.

After seeing Spy Kids on tv a few times, I finally realized that I remembered Alexa Vega portraying a girl about six years old in Little Giants (1994) and Carla Gugino portrayed a teenage girl named Chica in Troop Beverly Hills (1989) whose fictional age was about 16 I think. So Carla portrayed at least one character with a fictional birth date around 1972-1973 and Alexa portrayed at least one character with a fictional birth date around 1987-1988, and they portrayed mother and daughter in Spy Kids.

Actually Carla Gugino's birth date is said to be August 29, 1971 and Alexa Vega's birth date is said to be August 27, 1988, sixteen years, eleven months and 29 days later.
