Actress RHEA PERLMAN dreads milestone ages and refuses to celebrate her birthday. The former Cheers actress, who is 60 next year (08), insists she is a nervous wreck when her birthday approaches. She says, "I hate (birthdays). I have a very hard time with them. "As much as I philosophically tell myself that age is nothing, that time is nothing, that life is a circle and that there's no beginning or end, when I get to that goddam number I can't stand it, I run away on my birthday."
