15.8.5 Substantivation of the infinitive - infinitive as subject
As in English verbs can be substantivated. In English it is done by adding -ing, in French the infinitive is used.
c'est quelque chose d' important.
For him, eating is important.
Further, again as well as in English, a verb can be used as subject of a phrase, either as substantivated verb or as infinitive (in English). For French it does not make a difference.
est mauvais pour la santé.
Smoking is bad for the health.
quelque chose diminue le risque de se trouver au chômage.
To learn something decreases the risk of being unemployed.
