If you're an employee of a company that offers a SEP IRA, your contributions count toward your traditional IRA contribution limit rather than the limit for defined contribution plans. For example, as of 2013, you can contribute up to $6,500 if you're 50 or older, or $5,500 if you're younger than 50.

Certain kinds of knowledge may be especially vulnerable to skepticism. For example, an agnostic believes that knowledge of supernatural things cannot be attained.

Here doubt, suspending judgement, methodical investigation, testing and discussion precede any statement of facts. Sometimes the process takes years before consensus is reached.
