Of course, that’s true anywhere in the world… but there’s something sacred here. I don’t know if it’s because I’m Japanese, but I believe the wrestlers and fans who shared this space all felt the same. Maybe."Nakamura also mentioned that while he has some things left to do, his in-ring career is nearing its end."John Cena, AJ — they’ve all chosen to step away from the ring. It reminds me that my own time might not be far off. But I still have things I must do. I’m still struggling, still fighting, not knowing what tomorrow will bring. All I can do is live this day with everything I have. Thank you.
