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.
In a nutshell, Roth IRA contributions are made with after-tax money, while contributions to a traditional IRA may qualify for a tax deduction for the year the contribution was made. Contributions to an IRA for the 2016 tax year must be made by the tax-filing deadline in April. With the Roth, taxes are paid on the front end so that in retirement, all distributions -- including interest and earnings -- are tax-free. Conversely, the traditional IRA generally gets a tax advantage at the time the contribution is made, but distributions are taxed as ordinary income in retirement.
