You may get the feeling that Viera is holding Greg back on this wall. That may be the case to the uninitiated. You see, this is a finely oiled and calibrated climbing machine. With great skill and instinct, Viera shifts her weight left, then drives her heal strategically into Greg's left shin. She squeezes off her partner's air supply to raise the sense of urgency and then promises the return of life-sustaining air when they reach the top. Next thing you know it, they are at the summit. Ahhh, I knew climbing was often a "team support" with a team like this, why would one ever consider free-soloing. So it is the case with life?
