Most common age of people getting concealed handgun permits in Texas?

From Fox News:

People over the age of 50 are seeking concealed handgun licenses at a rate higher than any other age group in Texas. 

An analysis of state records by the Fort Worth Star-Telegram found that 57-year-olds last year sought the most concealed handgun licenses in Texas. In recent years, Texans aged 63, 52, 61 and 60 have also led the way in gun permits. 

Texas has more than 580,000 concealed-carry permit holders statewide. The Star-Telegram reported Monday that about 26 percent of those were issued last year. . . .
