Iron Woman BoA gets tired as well. Down to earth superstar BoA recently uploaded a funny picture of herself looking pretty tired after a hike. She wrote along with the photo, "I've hiked 2/3 of the mountain. Should I keep going or not???? I'm so tired I could die. T T Heaven and hell are in front of me.. T T" She's carrying a walking stick and has her head down probably because her face clearly shows how tired she is feeling. If she's this tired after a hike, how does she do concerts?
