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.
