Sorry I was being imprecise when I said daily in my original reply, when my main point was that consistency's more important than duration. IMHO, once a viewer base is established, one can be sustainable streaming ~3 hours twice a week. If that's still too strenuous due to her illness, then I'm even more sorry for her, and perhaps she should instead -- if not already -- focus her energy on applying for disability benefits / grants, and only treat streaming as a hobby.
