Is it ethical to represent your age as younger than your actual (birth date) age if the criteria below are met? Once a contact or date has occurred or will occur, how soon should the person be advised of your numerical age? 1st date, 2nd date? How do people feel about this approach? What criteria are missing from below?

Appearance - You actually do look the age you represent (face, skin, hair, genitals, etc) Health - You are AT LEAST as healthy as the average person in the age group. ( I know. It's hard to define). Emotional/Social Maturity- You are capable of relating adult to adult in a meaningful relationship Physical Activities - You can and do engage in activities typical of the age group. Perhaps some degree of spirituality (?) Perhaps some degree of sexual interest (?) [Given that not everyone chooses to be sexusl at various points] EXAMPLE: IF a person of actual age 58 looks 40, is quite healthy, has previously demonstrated the ability to keep a healthy relationship, believes in God and has some 'average' interest in sexuality THEN is it acceptable for her to represent her age as 40 on a dating app?

[In the above fictional EXAMPLE, just trying to illustrate a genetic person.]
