I enjoy watching them and so does my daughter who at the current time wants to major in biology. My youngest used to watch them, but got traumatized by some "nature being nature" footage and so turns down watching them. She sometimes still watches the wildkratts show. There is a female youtuber who does shorts about various animals, think squid and octopuses in a fun entertaining vein, but I'll have to ask my daughter what her name is. My sister and I have always been into science and science fiction. Some good authors if you want to read some mind bending stuff, after reading hawking, is Leonard Susskin, and Brian Greene (though I don't know how long it will be if ever, string theories can be proven/disproven).
