I graduated from life science 7 years ago and joined the finance industry. Looking back, that was the best decision I've made seeing how some schoolmates who are doing their postgrad now are thinking of leaving the industry but realised that they are too niched and too expensive to be hired outside science. There is also this stress of job security among them as research is heavily based on funding. Some labs are closing down or have to change direction to do research projects that are commercially viable to attract investors. It's a tough field to be in with limited opportunities and slow salary progression. Fresh biz grad in banks could get a higher pay than recent PHD graduate. So I feel unless one is really passionate abt research and is not concerned abt compensation package, don't limit yourself to a career in life science.
