The way they attack those weights... damn scary. Most of
them become damn buff after a while. But as usual, they
grades drop.
2 Hyphotheses.
1. Bad time management, and training requirements of
Dragonboat and canoeing causes them to slip in grades.
2. Bigger muscles, less brains. Nutrients (proteins
etc) normally meant for brain development gets sapped to replenish
and repair torn or worn out muscles. Brain's processing
capacity reduces.
I don't know which one is true, but I've rarely seen dragonboat
rowers or canoeists that score straight A's. Other sports
yes, but not these two.
Num 2 hor... not true hor
Num 1 is more likely
