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.
The IRS won't let you deduct Roth IRA contributions. The money in the account is not taxable and remains nontaxable when withdrawn as a qualified distribution. The tax-free status applies to all earnings, including capital gains, interest and dividends.
