Salt and Vinegar crisps

I recently discovered that I like salt and vinegar crisps. I was feeling hungry, and sadly S&V crips were all that were available. Faced between starvation and crisps I dislike, I figured what the hell, and took them. Oddly, I found them to be quite bearable. In fact I actually enjoyed the packet!

This worries me, as I have known all my life that I hate them. This either means that either I had a bad experience with a packet of particularly cheap and nasty S&V crisps as a child, or my tastebuds have changed as I've got older, making my tastes for food change too.

If the second case is true, then this worries me deeply, since if I have started liking foods that I disliked in the past, does it follow that I have also started disliking foods that I once liked? The trauma that I may suffer when I discover that a comfort food from my childhood now tastes vile may come onto me at the most unexpected time. Dare I risk eating anything that I haven't had recently, when there's a risk that it may make me physically ill, and shatter childhood memories?

The logical conclusion is, of course, to eat nothing but salt and vinegar crisps, but this may be a little extreme, and cause nutritional problems unless someone can find crisps fortified with vitamins and minerals.
