Z is a grown man and doesn't live with DT.Of all the things DT could help him with, this is the easiest. But I guess it’s one of those “easy to say, hard to do” things.
Z easily has another 2 cycles in him. He doesn't get hurt, can train hard and is just so unbelievably athletic. But if he can't figure out that he needs to live clean, it's not going to matter.
