Even viruses, which are not considered living but organic molecules, are composed of proteins. Ribosomes are composed of ribosomal RNA and proteins.

If you earn 5,000 points during your three-month challenge you then keep your gold status for a whole year and it only expires on February 28th of the following year.

British Airways announced today that theyâre introducing a lifetime status program. If you log into your Executive Club account you should now see your lifetime Tier Points listed at the top right, which includes all Tier Points earned in the past. Theyâve also introduced lifetime Executive Club Gold status after cumulatively earning 35,000 Tier Points. You typically need 1,500 Tier Points to earn Gold status, so this is the equivalent of lifetime Gold status after requalifying for ~23 years. On one hand that seems like a lot, though on the other hand there are no requirements as to what elite status you must have each year, how long you have to be a member for, etc.
