Life Algebra


How to solve this ‘Life’ Algebra ?

The simultaneous inequality equations with 3 unknowns {e, t, m}, resp. for energy, time, money.

It has no solution but we can get the BEST approximation :
Retire after 55 before 60, then you get optimized {e, t, m} — still have good energy (e) with plenty of time (t) and sufficient pension money (m) in CPF & investment saving.

Beyond 60 if continuing to work, the solution of {e, t, m} -> {0, 0, 0}.

Note: After death (e = t = 0), money is not yours (m = 0).
