Is it OK to date or love someone significantly older?

I am curious about what people think about this. Would you yourself date someone who is say 10 years or older? Or if a family member or friend was dating someone older than themselves? I guess the same could be asked about dating someone 10 years or more younger. Would you be happy for them or disgusted? I'm the kind of person that doesn't really take age much into consideration if I like someone and we get along really well. Even with friendships. One of my oldest friends whom I love catching up with is in her 60's and a majority of my friends are a few years older than me. I don't have many young friends. I think I went off track there, so dating, yay or nay? :)
