This is a sad thing that Most of us study science (Biology or Physics) back home and are inclined towards it even after we come to US. We just think it's so cool to study Science but infact it isn't unless you want to go study Medicine. Options after Bachelors in Life science is that either you work as a lab technician ($15/hr) or go to Medical School or last option is continue doing PhD (thinking one day you'll become scientist and your friends and family will be proud of you )...That aint right !

Sometimes your PhD in life science is not worth more than scooping an Animal Poop, washing test tubes or loading electrophoresis gel all day and you'll get about 50k for doing all that....This is the reality. Will you be happy with that ? Certainly not !

Those bagholders (PhD in biology or life science) will say anything now, they'll say oh how much i love science and all that BS..That's just a BS.

Unless you're extraordinary, your road will be rough with PhD in Biology. Keep in mind, we're only talking about PhD in Biology or life science degrees. There are some fields where PhD is a must and is well rewarded such as PhD in Statistics, Biostatistics...People in this field good money and job is not as hectic as PhD in Biology.

Decision is yours !

@Guy_tensed: I think you're better off terminating your program and going through different route! 
If you want a PhD for the money, or you can't thik of anything better to do, then yes, its a stupid life choice.
