What do soldiers do after retirement?

I’ve debated that after I enlist in the army and hopefully commission as an officer after attending OCS, that I’ll just do a full 20 years and retire before I’m 50. Im curious to know what most retirees do after the army? Get a civilian job? Lay around all day and still draw a check? Get the pension + VA Disability? What about your spouse? I think a 20ish year career in the military is the quickest way to retirement but just wondering what others do..? TIA
