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.
However, some older folks choose to apply for early retirement at age 62 or 63 rather than applying for disability. Even though this may seem an easier option, it can reduce the amount of benefits you are entitled to. You can get disability benefits up until full retirement age, which is 66 right now.
