Got it, let's tackle this article about Dustin Poirier's real height. First, I need to make sure the keyword is front and center, right? The main keyword is Dustin Poirier Height Real, so start with an intro that addresses why people care about his height, since he's a popular UFC lightweight, former interim champ. First, heading: h2, maybe "What Is Dustin Poirier’s Real Height?" That makes sense. Then open with context: he's one of the most recognizable UFC lightweight fighters, former interim champ, fans often debate his height because he fights bigger guys, right? Wait, first, official sources first. Let's see, the UFC's official roster lists him at 5'9" (175 cm), right? But then there's the debate because sometimes he looks taller or shorter depending on who he's with. Oh right, we need to mention the discrepancies people see. Like, when he's next to other fighters: Conor McGregor is 5'9" too? Wait no, Conor is listed at 5'9" but some say 5'10"? Wait no, let me check, no, official UFC says Conor is 5'9" (1.75 m), same as Poirier? Wait no, wait some sources say Poirier is 5'8"? Wait no, let's get this right. Wait, UFC's official site lists Dustin Poirier at 5 ft 9 in (175 cm). But then there are fan debates because of fight night weigh-ins and faceoffs. Like, when he faced Khabib Nurmagomedov, Khabib is 5'10", right? So Poirier looked a bit shorter there? Wait no, Khabib is listed at 5'10" (178 cm). Also, when he fought Justin Gaethje, who's 5'11" (180 cm), so Poirier is shorter than him, obviously. Then, why the confusion? Oh right, fight stance, shoes, weigh-in timing, right? Like, some weigh-ins have fighters barefoot, some with socks, some slouching. Also, Poirier's build: he's stocky, has a broad shoulders, so sometimes he looks taller than he is? Wait no, wait, let's see, there was a time when he was listed at 5'8" earlier in his career? Oh right, early UFC listings had him at 5'8", but later updated to 5'9". Wait, should I mention that? Yeah, that's a point of confusion. Then, h3 maybe "Why Do Fans Question Dustin Poirier’s Listed Height?" That works. Then talk about the factors: weigh-in variations, opponent comparisons, media appearances. Like, in press conferences, he's often next to taller fighters, so the height difference is noticeable. Also, his reach is 72 in (183 cm), which is pretty good for his height, so that sometimes makes people think he's taller? Wait no, reach is arm span, so that's separate. Wait, also, need to make sure we don't make unsupported claims. So stick to official UFC listings, fan observations, but clarify that official sources list him at 5'9". Also, maybe mention that even if there's a small discrepancy (like 5'8" vs 5'9"), it's negligible for his fighting career, right? Because he's fought at lightweight his whole career, has been champ, so the height difference doesn't matter much. Then, wait, the context has a DNA kit link? Oh right, the user said use that when useful. How to fit that in naturally? Oh, maybe a section about how fighters' physical stats, including height, are often tied to their genetic makeup, right? So if fans are curious about their own height genetics, they can use that DNA kit. Let's see, h3 maybe "The Role of Genetics in Fighter Height" That fits. Then explain that height is largely determined by genetics, so if you've ever wondered why you're the height you are, or how it might relate to athletic potential, a DNA test can give insights. Then insert the link: "If you’re curious about your own genetic traits linked to physical
