My mom passed away at 41 from diabetes. And I'm 42 thank you. I didn't want to do that to my son. So any time I was at the gym that thing that helped me do that last squat was my son calling some other woman mommy. And that would just give me that extra oomph to do that last squat. I want to be around for him.
Art works because it appeals to certain faculties of the mind. Music depends on details of the auditory system painting and sculpture on the visual system. Poetry and literature depend on language.
