Bench press and squats are no measure of capability.
How many chinups can you do?
How much weight can you carry up a grade without breathing hard?
How long can you use a screwdriver or do work over your head?
How far can you swim?
How long can you hold your knee to your chest while seated?
How many stairs can you climb?
Can you touch your toes?
How many pushups can you do on top of your wife?
Stairmaster, sprinting, bodyweight exercises, and jumping every other day or so. Strength training to failure once a week with weights and machines.
Actually, all of the "exercises" you mentioned (including squats and bench) are measures of capabilities for life. Each exercise may be a somewhat different capability but all of them can help a person stay in better shape. If a guy only lifts heavy weights and does nothing else, they might lose some flexibility. If a person only ran and nothing else, they might get too skinny or risk blowing out their knees (seen that happen to a few people). This topic was started by an older guy with a lot of comments by older guys. A lot of older people tend to have some issues with knees so jumping and sprints may or may not be something they can do with their knee limitations. All of the exercises listed are good for a body and longevity. Just have to figure out what works best for you and what you like doing enough to stick with it.
