Cian Healy reckons he's forever 21 - because staying young at heart is the key to staying relevant at high-flying Leinster.
Healy, who is actually 31 and is getting married during the summer, has seen a number of his friends and peers leave or retire.
Sean O'Brien and Jack McGrath will be among those bidding farewell to the province for pastures new after the PRO14 final in Glasgow.
He has been particularly "tight" with McGrath, given how they play in the same loosehead role and have been nip and tuck for the number one jersey for years.
"The pressure we put on each other pushed us on and we probably achieved things we wouldn't have achieved without each other," reflected Healy.
"It will be tough not having him there, Seánie and Nick (McCarthy) and the other lads."

But losing friends and colleagues of that calibre - Jamie Heaslip is the stand-out other - from the set-up hasn't lessened the enjoyment for veteran Ireland prop Healy, who continues to play at the highest level week in, week out.
"It's terrible to see lads leaving or retiring or anything like that," said Healy.
"You have two ways of taking it - you sit there as the old boy or you shape up and go in and be one of the young lads.
"And I love that. I love the craic you have with the lads, and pretending that I'm 21 and living off them a bit.
"So it's such a good place to come into work and to train and play around.
"The buzz is deadly and a lot of that's coming from the young lads and they're driving that on.
"There's no point sitting there thinking that you're an oul boy in training, that's not going to do you any good."
Healy has seen the dynamic in the dressing-room change over the years from a scenario where young players have to bide their time and learn their trade to now, where they come in almost fully formed as pros.
James Ryan is a prime example, but at Leinster there appear to be tonnes of examples.

"They're coming in now as full professionals from the school system or the academy system," the Clontarf man remarked.
"You can't single them out. They're great craic, they're craic to be around in the changing room, great for a night out.
"We've had a few squad nights in houses where you don't go out, you just all stay together and it's not just the old boys turning up, everyone turns up and it's a good vibe to be a part of, that no-one feels singled out."
So does he have to tell the young guns to stop jumping on his couch?
"Not at all," laughed Healy. "I'd spur that on. You have to let a bit of wildness slink in."
Healy and his fellow front rows Tadhg Furlong and Sean Cronin showed a bit of their wild side in last Saturday's win over Munster - the three of them combining for Cronin's try.
Healy grinned: "That’s nice, isn’t it? I enjoyed that.
"I didn’t have the energy to celebrate like Tadhg but I enjoyed it. At least we were doing something from training! It was a straight drill.
"We'll take the bit of credit we got in the meeting and shut up for a while."

Healy, and Leinster, are determined not to lose a second final in a row after he experienced his first loss a Champions Cup final - after four previous wins.
"Not great," he said, explaining how he felt afterwards.
"It was tough. We turned the page quickly in here and got moving on the week.
"It was creeping up on me during some basics stuff, cooking dinner thinking about the ‘what ifs,’ which you have to slap out of your head a bit and have to stay focused.
"It just showed to myself that it did hurt. I don’t want it to happen again".
