Last week I received my first box of Soylent. It’s a beige-ish shake drink that would be a perfect source of nutrients on a long space voyage. Just add water! Sometimes I refer to it as Shake Weight since you’re supposed to shake it for 30 seconds to mix.
Soylent is now the first thing I eat each day. It’s great for other meals too, but it really solves the “breakfast problem” for me.
