From what I can gather it seems that the people who enjoy the extremes are people that perhaps haven't had their lives affected by that type of weather. Try to read that sentence in a polite calm way as it isn't having a go at anyone. I use these forums because not only am I interested in weather and climate but I am fascinated by forecasting and looking for trends, so not all of us are extreme weather enthusiasts.
My whole life is pretty much dependent on the weather, we have a farm to run, I help with looking after wildlife habitats and my main hobby is butterfly hunting. I enjoy bike rides as the exercise makes me feel good, the sun makes me happy because I suffer from SAD. I also know the consequences of extreme weather, my great great gran was killed by lightening, My car was hit by a tractor sliding on ice, my friend was injured and her car written off when she hit flood water and I've had a couple of close shaves with lightening and was once indirectly hit.
Yes heat kills too but I'm not looking for a heatwave, just blue skys, warm sunshine with a temperature of around 20c.
