Answer:
If one were to use 5 billion years as the age of the universe and 75 years as the average human life span then
T = 75 / 5 E9 = 1.5E-8
The number of seconds in a year is 3600 * 24 * 365 = 3.2E7
If t = N * T seconds in a year * fraction of human life span
t = 1.5E-8 * 3.2E7 = .48
A human life span is about 1/2 second compared to the life of the universe if the universe were compressed to a single year
