A moderately religious Jew comes to the rabbi for advice.
— Rebbe, I'm going on vacation to the sea tomorrow...— Congratulations, Mazel Tov.
— But, Rebbe, I will go to the beach there every day...
— Well, that's fine...
— But, Rebbe, there will be women in swimsuits on the beach there... Is it allowed for a Jew to look at a woman in a swimsuit if she is not his wife?
— You can.
— Rebbe, what if there are nudists there? Is it allowed for a Jew to look at a completely naked woman if she is not his wife?!
— You can.
— Rebbe, are there any things that a devout Jew should not look at?!
— Of course. For example, at electric welding.
