Thomas L. Jones appeals the decision of the magistrate judge upholding the Secretary's denial of Social Security disability benefits. Jones contends the Secretary's decision is not supported by substantial evidence on the record as a whole. Specifically, Jones argues the administrative law judge committed error in finding that Jones did not have a severe impairment and, alternatively, in finding that Jones could perform a full range of sedentary work activity. After a careful review of the record, the briefs, and the reasoned decision of the magistrate judge, we affirm. See 8th Cir. R. 47B.
