Predator If It Bleeds 76

Everyone else was scared off by the wording of the personal injury waivers. The fighters could choose to train at any time. Never against each other, of course. But Chiba seemed able to tap an endless supply of willing sparring partners. Fix spent a lot of time watching the other fighters train, studying their moves, gauging their skill, calculating how much was natural talent, how much was learned technique, and how much came from

He'd been able to do it growing up in the slums of Gary, Indiana, fighting for food money, fighting for money to keep his three younger sisters
fed and dressed and healthy after their single mother rode a needle into the big black. It served him well, even against better fighters, when a judge suggested he box in a local gym or spend six months in juvie. It helped him when another judge suggested that the military might be a better calling than working a prison detail mining precious metals on an asteroid. And it had kept him alive all through his twelve years humping battle rattle around the solar system.-pg.416-417 chpt.16
