Great post @mariusfebruary. On the one hand, 45 offline hours sounds like a rather short span of time, but I can imagine how hard experience can it be. A few years ago, two weeks of being offline (without any access to the phone) was rather easy for me, but nowadays I can't imagine such challenge. It is probably because my phone controls plenty of things, I have my money there (most in crypto ;) ), navigation, Steem, access to the knowledge and many many more.
However, I can imagine how relaxing such experience can be and I think everyone should try for at least couple of days. Many of us rapidly need such therapy :)
