Does Arnold is still capable for doing Terminator role once again???

really not at all.. but he is much healthy and still he has the power. even in his last terminator film, he took much risk for performing that role. he took special care for his arms and in an interview he mentioned that he did wrist curls continuously for 45 days for getting grace look. but this not the proper way for building arms. he take risk for his fans when they see him on screen. it is much doubt that arnold will play once again a role like that
