I think that's fairly normal. We know the past but can at most make an educated guess about the future. Knowing something for sure gives us a feeling of safety, while not knowing tends to make us insecure.
Not sure if that's a general phenomenon or just a personal problem but I find that I get very much thinner-skinned and I increasingly dislike changes the older I get. Perhaps that is because young people have more emotional resilience and a larger supply of inner strength. When we get old, we burn out and have to replace inner strength with stubbornness. Also, we are less flexible in our views and ideals. (LOL funny that joints and soul get stiff at the same time

)
