Problem Sum
J lives in Singapore. He is currently one of the 80% from the average working Singaporean. Based on the above scenario, calculate his life statistics.

Step 1:
Let X be the the potential retirement age

hence X = 70 years old

Step 2:
Average Working Lifespan = (retirement age) - (Age to start work)
Average Working Lifespan = 70 - 22
Average Working Lifespan = 48 years

So, average working lifespan is: 48 years

Step 3:
Life Statistics = (Avg working lifespan) X (Wake up, Go to work, Sleep)
Life Statistics = 48 X (Wake up, Go to work, Sleep)

Conclusion
Hence, an average Singaporean will work like a DOG for 48 years in the near future.
