Go outside and play. This is useful advice both for fitness and for general wellbeing.
The index of my brain is not working today, so I don’t remember and couldn’t locate the place where I read that an increased sense of depth perception can trigger a sense of wonder (William James? Charlie Tart? Carlos Castaneda? One of those altered states kind of guys…), so you will have to take my word for it that someone did the research. Point is: go outside and look up; it will make you happier. If you happen to be breathing hard at the time, so much the better.
It’s a lovely day. Your bike is calling.
