The main facets for an extended life , I think, are partially in the genes; number two is life style, which includes balanced diet and normal exercise. I go, work and swim every day. Nevertheless, I think too much workout can be bad as a result of over-stress; often people who workout also much time each day die early.
The nice thing about’Arrow’is we never say never on the show. Preferably the show may have a nice extended life , and all types of things can potentially happen.
