For example, 11% of the worldâs population was at least 60 years old in 2010. But fully 20% of Jews around the world are 60 or older, as are 15% of Buddhists, 14% of Christians, 14% of adherents of other religions (taken as a whole), 13% of the unaffiliated and 11% of adherents of folk religions.
The Answer: All sunscreens have an expiration date printed on the bottle. Typically they last a year or two, and most are good for three years. The safest bet, naturally, is to ditch old product and replace it. But in a pinch, hereâs a secret: Sunscreen is still good for six months beyond its expiration date. In that period, itâs better than nothing. But after that, itâs time to suck it up and buy a new bottle.
Bath oil: One year to use up that gorgeous bottle with the lavender stems; don't delay. Sunscreen: Check the package for an expiration date, but if you still have last year's opened bottle of sunscreen, you should abandon it. Aim to use it up within six months of first use; if you don't, you're probably not using it enough. Mascara and liquid eyeliner: Three to four months once you start using it.
