Unlike insurance companies, we don't benefit from customers passing away.

If customers are living longer, our algo's slows down the capital payouts which means that we earn fees on more assets for longer.

Therefore it makes commercial sense for us to give customers tips to help them live longer.

For example, I just found this today: https://academic.oup.com/ageing/article/51/5/afac080/6572254...

As opposed to killing customers because their treatments cost too much? (Which happens everyday by denying coverage, unlike the fictional plot device of Tontine as a motive for murder.)
