cycling does put quite a load on the hands and wrists. how the handlebars and grips are set up makes a considerable difference, and from some recent test rides, the bikes that have an upright position, more weight directly over the pedals (some now are semi-recumbent, the legs pushing a bit forward and down), take a lot of stress off the wrists and thumbs.
you have a lovely family, from the photo. our large male feline likes sprawling across the top of our grand, but is not fond of the sound of it being played. luckily for both of us he spends most of his waking hours outside. just from reading about it, the summers in northern latitudes sound tiring for the majority of folks accustomed to resting at night. have been night oriented myself since very young and have little trouble sleeping at mid day or surviving with naps ; it was the winters that affected me much more in somewhat northerly states in the u.s., nothing in the lower forty eight of course like the Baltic states or scandinavia or alaska.
