Any good words/phrase in a birthday card for 55yr old?

Question

I want to send a 55th birthday card for a male friend of mine and I'm looking for any good words / phrase besides just ' Happy birthday'.

I need a decent line, not naughty one.

They don't sell any good birthday cards for middle-aged or elderly people here in Japan at all!

Please give me good examples! Thank you.

Answer 1

You are in the prime of your life. You have learned more than you ever will again. Your powers of intellect will never be better. Your wisdom is immense and valuable. You have got this far and there is no reason for you to stop now.

By the way, I am 55!!

Answer 2

55

10 more years till retirement.

Answer 3

You're 55 - you look 45 and act 35 !

Answer 4

In all the years I've known you, I've never known you to be 55.

I used this phrase for my grandma's 65th birthday, only substituted the 55 for 65.  It cracked her up.

Hope it helped.
