Why doesnt everyone just take cialis everyday?

whats good guys

been looking into daily cialis mainly for bp and gym pumps. but the more i read about it the more crazy benefits it seems to have for your heart and even cognitive stuff.

the side effects seem super mild and u can just lower the dose if anything pops up.

so what am i missing here? why doesnt literally everyone take a low daily dose of this? are there actually bad long term sides that people ignore or is it just because of the price?
