XRebel Redesigned to Scientifically Make You Smarter

It’s common knowledge that learning is multi-sensory. However, in a study we made up, we found that 71% of developers are sensory-deficient. In the lab, we found that by exposing users to a sensory bath, we force open the vaccuuminal cones in the neurons, essentially massaging the sensory receptors in the brain to allow more data intake. Neurons can scientifically absorb 147% more information than sensory-deprived neurons. Now, that’s something.
