$SEX for money!

Statistics say that people have sex more often on weekends and much more often on holidays, so the SEX graph can be represented as flat on weekdays, slight jumps up on weekends and strong jumps on holidays.
At the same time, the desire for sex will never fall - every small jump in the rate on weekends and every big jump on holidays will record a new high in SEX)
And of course, we will see the biggest growth in the last days of December and the New Year holidays)
