For one, how good the royal dad looks in a tux

Prince Harry celebrated his 37th birthday on Wednesday, and with every year, the Duke of Sussex gives us more reasons to love him. Here are just a few...

1. His red hair.
From top to toe, Harry's a rare gem.

2. His smile.
That face! Who could say no to that face?

3. How sweet he is with children.
The royal gave us many glimpses of what he'd be like as a dad in his teens and 20s — now in his 30s and beyond, he has son Archie and daughter Lili to dote on!

4. His willingness to tackle difficult issues.
In a joint statement in August 2021, Harry and wife Meghan addressed several generation-defining struggles, imploring, "we are not meant to live in a state of suffering. ... It's easy to find ourselves feeling powerless, but we can put our values into action — together."

5. His dedication to veterans.
He's participated in events like Walking with the Wounded and hosted the Invictus Games around the world. You might say he's a veteran's best friend.

6. He doesn't look for recognition for his work.
And often does under-the-radar engagements, like his visit to an HIV hospital and his secret trips to Africa.

7. He's not afraid to get his hands dirty.
While in Africa, Harry was one with nature — literally. Simson Uri-Khob, CEO of Save The Rhino Trust, said: "He likes to be out there, sleeping under the stars knowing that he is close to dangerous animals."

8. He texts back quickly (according to Margot Robbie).
Men of the world, if Prince Harry can do it, so can you.

9. He's playful with his niece and nephews.
Harry once told Good Morning America that he's always having fun with Prince George: "Usually I'm throwing him around the room and stuff."

10. He's spontaneous.
Longtime royal photographer Chris Jackson told PEOPLE, "Harry has a real energy to his engagements" and brings "an element of unpredictability which has always been special."

11. He likes to keep it wild.
Harry is passionate about his work with conservation organizations, saying in 2020: "I've always believed that hopefully we can leave the world in a better place than when we found it."

12. He has friends around the world.
From Jamaican sprinter Usain Bolt to singer Elton John to U.S. First Ladies Dr. Jill Biden and Michelle Obama, Harry take squad goals to a whole new level.

13. He's open about his emotions.
Since the 1997 death of his mother, Princess Diana, Harry says he's learned to open up. "Everything can be okay," he said. "But I really regret not ever talking about it for the first 28 years of my life — I never talked about it."

14. He's adopted his mother's causes.
He's dedicated his life to making his mother proud, and Harry is doing just that working with causes that were close to heart, like destigmatizing HIV and AIDS.

15. He owns his flaws.
Harry can't sing, and he'll admit it.

16. He keeps things cordial with his exes.
His former girlfriend Chelsy Davy says they'll "always be friends."

17. He's an expert tickler.
Just ask Mia Tindall.

18. He knows how to put on an awesome event.
See the Invictus Games for proof.

19. He loves Disney World.
Including Space Mountain (which he went on 12 times a kid) and Splash Mountain, which he rode as an adult.

20. He goes out of his way to make people feel special.
After he gave former British army staff sergeant Katie Kuiper a kiss on the cheek, Kuiper said: "I feel invisible a lot of the time because of the way I look. He made me feel special."

21. This video with the Queen.
Not many people can convince Queen Elizabeth to participate in a mic drop — but Harry can.

22. He's thoughtful and sentimental.
While Harry and Meghan chose a wholly unique name for Archie Harrison, they opted for something deeply meaningful for baby No. 2, honoring both his grandmother and his mother with the name Lilibet Diana.

23. He's athletic.
The man plays polo, rugby and soccer.

24. He can take a joke.
Even if you're calling him sausage.

25. He had a good attitude about everyone asking him when he was going to settle down.
Good thing, too, because he got that question a lot before he married Meghan!

26. Did we mention he looks good in a tuxedo?

27. ...and workout gear.
He doesn't need to dress up.

28. ...and jeans.
Who doesn't love everyday Harry?

29. He's a man of action when it comes to supporting causes he cares about.
He even took an HIV test live on Facebook.

30. He makes savvy pop culture references.
He's even watched The Crown! (But no, he's not like Bridget Jones.)

31. He says the sweetest things about Diana.
He told PEOPLE she's often on his mind when he's working with charities. "I don't have that many memories of my childhood with my Mum," he said. "I don't say 'Right, I'm going to get involved in that because that's what my Mum would want me to do,' though inevitably once I'm doing it I think, 'Do you know what? She'd probably love this.'"

32. He's always working to make her proud.
"All I want to do is make my mother incredibly proud," he told PEOPLE. "That's all I've ever wanted to do."

33. And those close to Diana believe he has.
The princess's confidante Sarah Ferguson told PEOPLE in July 2021: "If [Diana] were sitting with me right now, I know she would say, 'I am so proud of both of my boys and the wonderful wives they have chosen.'"

34. He defends the ones he loves.
When Prince Harry and Meghan Markle began dating, he released a rare statement condemning the "the outright sexism and racism of social media trolls and web article comments."

35. He's an adorable dad.
In the royal couple's debut as parents, Harry lovingly cradled his son while the Duchess of Sussex proudly looked on.

Harry became a fur father to Meghan's beagle Guy when they first got together, and the couple later added a pooch named Pula to their pack.

37. He's as committed to maintaining a regular life as a royal can.
During a string of pandemic-era virtual meetings (relatable!), Harry and Meghan have gave royal watchers glimpses of their home life, which features cozy couches and family photos.
