I'm trying to do this in swift and I was wondering if there was a more efficient way:
if(doesSmoke)
yearsTotal = yearsTotal - 7.5
if hoursSleepAvg < 7
yearsTotal = yearsTotal - yearsTotal / 100.0
if hoursSleepAvg > 8 {
yearsTotal = yearsTotal - yearsTotal / 100.0
There are a lot more if statements. Does anyone have a solution?

You can consolidate different types of if statements into methods.
For example
main()
yearsTotal += accountForSmoke()
yearsTotal += accountForSleep(yearsTotal)
func accountForSmoke() -> Double
return doesSmoke ? -7.5 : 0
func accountForSleep(_ yearsTotal: Double ) -> Double
if hoursSleepAvg < 7
return -yearsTotal / 100.0
if hoursSleepAvg > 8
return -yearsTotal / 100.0
