Infectious agents such as bacteria and viruses are the most frequent causes of gastroenteritis in the US and worldwide. Infections cause diarrhea and other symptoms by causing inflammation of the gastrointestinal (GI) tissue.
Remember, your Traditional IRA is tax deferred, while your Roth IRA is tax free... So, assuming a income tax rate of 30%, you really end up with... $20,933.70 in your Roth IRA, but only $14,653.59 in your Traditional IRA. That's the difference between an IRA that's tax deferred and an IRA that's tax free.
Roth IRAs generally offer better tax savings, but they are contingent on a number of factors, including your eligibility to make contributions to the accounts based on your income. The main benefit of Roth IRAs is that they allow you to make tax-free withdrawals, whereas traditional IRA contributions are tax deferred.
