You can cheat your kid in hockey. More ice than everyone else, more privates, hockey only, year-round, starting at seven. And it works -your kid is better at 10, 11, 12. Then 13 or 14 hits. Physical development kicks in, and the kids who can actually train hard start training hard. The ones who are fresh take huge leaps. The ones who've been grinding for six straight years find out they're running on empty. You didn't give your kid an advantage. You borrowed against their future.
