Maybe he realized that he WILL have to take responsibility for having a kid (unlike being able to largely avoid the responsibility of acknowledging with genuine contrition the sins he committed against cycling and clean sport

) and perhaps he didn't bank enough of that super-star, pre-dope cheat loot, and so realizes that any hope he has of earning the kind of money that would be impossible to make w/o a trade or university education in Italy rests on his not testing positive a second time...b/c he has a kid to look after now and can't afford to get caught again (literally)...
But who knows. That's f'd tho when your partner gets popped nearly two years after you do for the same substance...and she was racing at the int'l level as far back as 2003/4, eh, so she probably didn't lose her PED virginity to CERA in 2009-10!
