A Civil Engineer and a Doctor (Riddle)

Justin, a civil engineer and Mark, a doctor, are both in love with the same woman named Jessica.

Both Justin and Mark know of each other and are in competition to win Jessica’s heart.

Justin had scheduled a date with Jessica but unfortunately, his boss asked him to go out of town to help complete a tunneling project which would take 5 days, however, Justin assured Jessica that he’d be back on the 6th day to take her out on the date.

Before Justin left, he gave Jessica 5 apples. Why?

Because an apple a day would keep Mark, the doctor away for 5 days until Justin got back in town.
