We show that the probability density function (PDF) of the increment, $W(\\tau)$, of a particle's energy over a time-scale $\\tau$ is non-Gaussian, and skewed towards negative values. This implies that, on average, particles gain energy over a period of time that is longer than the duration over which they lose energy. We call this $\\textit{slow gain}$ and $\\textit{fast loss}$.
