Hi all...

I've been offered a PhD place, but am unsure if I want to commit myself to this topic for 3/4 years. What do people think about how PhD topic affects your future career path?

Basically my offer is for bacterial molecular genetics - investigating the genome of a bacteria, but I was turned down for investigating the effect of probiotics on irritable bowel syndrome, something I had my heart set on! I'm still getting over this but I don't want to lose track of goal of getting a PhD and having a research career. I'm not sure if I should accept this offer, or wait for something else to come up, possible waiting until next year. I'm 30 this year so also concious of time flying by!

I'd appreciate any advice anyone may have.

Thanks x x
