Sometimes I sleep in a hammock and it helps a lot. I have a Grand Trunk and an ENO, both doubles, that fit me and my girlfriend comfortably. I prefer the Grand Trunk, but I use the ENO mounting hardware with it.
Normal adult cells use a small energy plant located inside them to produce most of their energy needs from oxygen, this is an aerobic process. In contrast, cancer cells rely mainly on the first part of the energy production process dependant on glucose (sugar), this is an anaerobic process.
Two pathways of anaerobic respiration in cells are fermentation pathways, one producing ethanol and the other producing lactate. Both fermentation processes replenish the necessary NAD + for glycolysis to proceed with its net yield of 2 ATP molecules per glucose.
