As someone who already had the virus and was looking for some actual justifications for whether a vaccine was necessary for me or not (and hoping not)... this seems like a pretty well-sourced and reasoned argument in favor of getting one. What do you guys think?

Carrot Tan

The idea was to eat a lot of carrots or take a daily high dose of Beta-Carotene to fix my awfully pale skin complexion.

But apparently high doses of Beta-Carotene have been linked with significantly increased risk of cancer and all-cause mortality rates in smokers or ex-smokers (I quit a year ago).

Are there any alternatives? I hate how my face looks anemic.

Probability

A certain RPG video game will sometimes give you an option to double the experience you earned that battle. If you choose to play a game, you randomly get one of three options:
>1/3 chance doubled XP
>1/3 chance to get standard XP
>1/3 chance to get zero XP
You can choose where to use this, including boss fights. When should you play the game and how often?

Nothing happened and after a minute I stopped it to put it on and resume.
Why do centrifuges need rotor lids anyway? The centrifugal force will firmly keep the tubes down anyway. It spinned fine without it. I know people even died due to loosely screwed rotor lids flying through walls at high speed, why do we need them?
