There's a hidden assumption in your argument that activities are isolated from other considerations, and these would indeed be inherently limited by our biology (hence why one of your 3 constraints is always violated).
But perhaps:
1) Activities performed in pursuit of a higher purpose can be fulfilling.
2) Higher purpose can be found in identifying and overcoming limits.
3) Limits are unbounded in an infinite universe.
Therefore, there is an infinite supply of fulfilling activities (and maybe truth-seeking is one).
Good point Luis. The fundamental assumption was that we will have figured out the biological limitation side, but you're right, in reality it won't be zero rate of decay, but rather full repair (so some decay but 100% rate of repair for any damage).
Higher purpose seems to be a common thread in such ultimate actualization question. To dig deeper.
The infinite limits/ constraints are also interesting concept. (My temporary conclusion is that we actually need some constraints, some limit, or even some suffering, to actually live a life worth living.)

Thanks for your interesting thought as always :)
