Just sounds like an excuse to be lazy imo

there are many people who come from very similar backgrounds yet take very different paths in life. Although the events pertaining in their lives are not identical, their background is relatively the same.

On the flip side

I remember reading a study on a selection of twins that were separated at birth to very different families, yet ending up in a similar lifestyle in terms of likes, dislikes, jobs, hobbies, etc.

So I guess in a sense I believe that a lot of our actions are biologically engineered into us before birth, however, just saying yoloscrewit, because you have no "free will", then going along and doing as you please because of this is rather, idiotic.
