Three birthdays, and a coincidence involving powers of prime numbers
The very warmest of birthday greetings to 
sparktastic, who today reaches a prime-power number of years. Happy birthday to alex_holden too, who is the same age. Also to latexiron whose age, while not a prime power, is fannishly significant -- and who, by reaching that age, ensures that between the three of them their average age is a power of a different prime.
