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.
Unlike traditional IRA contributions, Roth IRA contributions aren't tax deductible. Therefore, contributing won't decrease your taxable income. For example, if your taxable income is $50,000 and you put $5,000 in your Roth IRA, you'll still be taxed on $50,000 of income.
