How long could we make lobsters live?

Lobsters don’t really age, so you might be asking
>why do they eventually die
Well, there are several reasons for that.

>molting
Lobsters continually grow, because of this the molting will eventually require too much energy. Death from exhaustion ensues.

>infection and shell damage
Some lobsters will stop molting when they get old, this results in the shell eventually breaking or getting an infection.

These reasons for death sound... preventable.
What if we
>stopped the lobster from molting
>sterilized the tank
>gave the lobster antibiotics
>and prevented it from doing heavy activity
How long could it live then?
