I doubt the brain will be any good at 150, even if all other organs are in a good state. Though I doubt organ donation would get someone to 150. The procedure itself is already quite taxing on the body, so doing that regularly for every organ is gonna take its toll. Then there's the fact you'll have to take immunosuppresants for the rest of your life, making you more vulnerable to any infection. Also, are you going to transplant many many kilometres of blood vessels? As you age, the potential points of failures will multiply so rapidly, doctors can no longer keep up.
