will it ever be possible to stop people from dying, as death and the processes of the body that keep us alive, all come down to chemicals, which scientists could eventually put back when those cells die

The retirement of many baby boomers as well as the desire for more engineers means that companies are highering more and at a higher pay. Is it worth it to go to graduate school for two years before entering the work force? Those two years could be more influential in your career working rather than obtaining a degree. I plan on going into technical consulting, eventually obtaining an MBA and going into the corporate world. Does that change anything? I'm currently a Junior pursuing a B.S. in Mechanical Engineering as well as a B.S. in Mathematics from the University of Illinois U-C. Thanks.
