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.
Traditional IRAs give a tax deduction when you contribute but are usually taxable when you withdraw. Roth IRAs, on the other hand, give no up-front tax deduction but you typically owe no taxes when you withdraw. You can think of a traditional IRA as tax deferred and a Roth IRA as tax free.
