As a 35 y.o. currently idle, life feels like a massive drag. I feel sleepy in the late afternoon from the antidepressants so I stay up a little later at night as a result.
I learned early on that I am not a people person so I could care less about relationships and friendships, it seems futile and pointless now and I have nothing to offer (physical, personality or ambition wise) so I get stuck into my interests when I have the time.
I have an interest in open source software so I have a laptop with Linux installed to tinker with when I'm bored.
