What do you think is too much of an age difference, or how do you see your generation gap?

Example: Jack is 28 years old, Jane is 18, Bill is 45, Tom is 35, Corey is 23, Kelly is 30.

Jacks answer: In his eye Jane and Bill are not in the same generation, but Corey, Tom and Kelly are. So his answers is -5 years younger to +7 years older. If Jack enters in 23 and 35, his answers will be rejected.

Kelly's Answer: Thinking along the dating line; She wouldn't date someone that is 10 yrs younger, or date someone that is 10 years older. So Kelly's answers would be -10 years younger to +10 years older. If Kelly enters 20 and 40, her answer will be rejected.

Reason for rejecting answers: We are going to use this to check and see if the user has read our examples. Yes we have taken into account for, if a user is 60 years old and they answer 40 and 70. Just like a user that is 22 enters in 18 and 26.
