Thank you for attention to my post. You know in the youth we often don't understand that thing which parents or teacher want to teach us can be useful for our future life but after years or ages we can look on past from different point of view. Also when I was building this garden house or shed as you call it I thought that it can be great if I learned sume building skills before)...

Also about missing physic work (physical activity) I understand that feeling especially last year when I have remote work. I try to be as active as it possible. Try to ride on my cycle, go with kids to kindergarten or work in garden. Even my second half couple times suggested to sell our apartment and buy house))
