Why is it when we try to do something cultural we end up doing the kids activities?

Unfortunately Zara and my Wednesday day trips into Scotland had a short lived life but we did start trying to at least venture into Edinburgh and visit museums, etc. Zara and I really only have patience for museums for about 30 minutes and after trying to increase our knowledge of Scottish culture always end up doing the kid activities instead. Why should kids be the only one's to have fun at a museum? The National Museum of Scotland has awesome kids activities from trying on viking costumes, to corsets, to driving an F1 car and testing your reaction time. Also the National Museum of Scotland is the home of the stuffed Dolly, the first cloned sheep. Dolly was cloned just outside of Edinburgh (a fact I learned at the museum before I started playing with the kid stuff). In addition to our museuming we also tried a fried Mars bar (a Scottish delicacy) it was surprisingly delicious although you could feel your arteries clogging as you ate it! Scotland's eating habits are about as good as the South's they like to fry everything here and take it down with a pint, oh the good life.
