A man with a beer belly is sparring with a high school student (11/23/2023) 

Japanese high school boxers are amazing! I think they could easily get a B or A license if they got a professional license.
They don't fight like old-school boxers, standing still and exchanging punches. They easily hit and then disappear.
They're too much for an old man like me lol
On a separate note, even though I lose 3 or 4 kilograms of water every time I practice, why do I get a beer belly? I don't even drink 3 or 4 liters of water a day...
