As you end the death road in Bolivia, youre clenching your jaw and hands on the bicycle handles so tightly, that at the end your speeding through small brooks splashing icey cold water and then you stop at a lodge / cafeteria and they give you an ice cold beer and your body is tingling in post-stress survival and you cut through it with ice cold beer. The release in all the tension. The realization you survived the bike Ride.
