re: Which potion would you drink and why?

I usually mix my potions but I'll go top 3 if I only get one as:

1. Red, money actually can buy happiness if you have debt and bills
2. Time travel anywhere - invest in something you know gets big and you're rich anyway? Is that allowed?
3. Stay young forever - but does that mean I have to commit suicide to die or can't die at all? The world news is sucking more and more every day idk if I'll want to be around forever, let alone in 20 years
