Correct. The Press select to use an item option wasn't introduced until the Gold/Silver/Crystal series of games. In the later games, simply selecting a key item would show 3 options-Use, Register (in G/S/C it's SEL), or quit. The middle buttons sets it to Select.
In order to receive Social Security disability benefits as an adult, you must be 18 years of age or older, and permanently residing in an American state or territory. Figure out your work credits. Generally, to be eligible for benefits, you must have worked in the recent past and earned a certain amount.
You cannot get SSDI if you become disabled after full retirement age. But, many people younger than their SSA full retirement age may be eligible for the Social Security Disability Insurance (SSDI) program after retiring early from the workforce. It does not matter whether the person ever intended to work again. The health problems would be disabling for at least 12 months.
