Oldest American Man Dies at 110
C. Conrad Nelson, the oldest man in the United States whose age can be verified, died in a nursing home in Rockford, Ill., on Tuesday, the Rockford Register Star reported.
Nelson was born in 1904 in Kymbo, Sweden, but lived in Rockford most of his life, working as a carpenter. He stayed in his own home until the age of 102, the paper said.
Larson attributed his longevity to lots of exercise and a bowl of oatmeal every morning. Speaking to the Register Star on his 109th birthday, he said, ""I can't complain. I feel good and I haven't been sick for a long, long time."
George H. W. Bush Hospitalized for Shortness of Breath
Former President George H.W. Bush, 90, was hospitalized Tuesday night in Houston after experiencing shortness of breath.
Bush was under observation at Houston Methodist Hospital as a precaution, according to spokesman Jim McGrath, the Associated Press reported.
Bush spent almost two months at Houston Methodist and was discharged in January 2013 after being treated for bronchitis and other health problems, the AP said.
The former president no longer has the use of his legs but in June celebrated his 90th birthday by making a tandem parachute jump in Maine, where he has a summer home.
According to the AP, he was most recently seen in public in November when he watched a Texas A&M University football game while seated in his wheelchair, in the company of his son, former President George W. Bush.
Nearly 2 Million New Enrollees for 2015 'Obamacare' Plans
More than 1.9 million new customers have signed up for individual insurance plans for 2015 via HealthCare.gov, U.S. Department of Health and Human Services Secretary Sylvia Burwell said on Tuesday.
That brings the total number of enrollees who've signed up through the site to more than 6 million, with the other 4.5 million people being re-enrollees from last year, NBC News reported.
HealthCare.gov markets individual health care coverage plans in 36 states. According to Burwell, the latest numbers do not include plans sold by state-run exchanges, including high-population states such as California and New York.
