Tax deferred investments not only help investors avoid cash outflows for taxes in the immediate future, but they can help investors generate higher returns. That's because the money that would normally be used for tax payments is instead allowed to remain in the account and earn a return.
Glial cell: A supportive cell in the central nervous system. Unlike neurons, glial cells do not conduct electrical impulses.
Myelin is produced by glial cells (or simply glia, or glue in Greek), which are non-neuronal cells that provide support for the nervous system. Glia function to hold neurons in place (hence their Greek name), supply them with nutrients, provide insulation, and remove pathogens and dead neurons.
