Cool clear water every time.
In fact distilled water to remove the chlorine, aluminium sulphate etc. Every 2 gallons treated tap water leaves a foul smelling brown gudge at the bottom of the tank. The aluminium rots your brain , goodness only knows what a regular intake of chlorine does ?
I used to drink two cans of beer per day but decided to cut it out in an effort to keep the weight down. I'm not obese but had those few kilos too much. Now, I only drink at Christmas and birthdays. My family put it on the table, otherwise I would not. I dislike water and do not touch soft drinks, The alternative is difficult, especially with the heat we get here, in summer. I've found Vichy Catalan to be a good alternative. A "quicky" hot drink, for me, is Nescaf'e. which is quicker to prepare than tea.
My advice to younger people is, knock off the booze. Alcohol is as bad as tobacco.
I expect some joking answers but I am serious about this.
Does anyone remember that film " The days of Wine and Roses"? Jack Lemon. My wife was a non-drinker and she started on rum and oranges, when we were married, because I liked it. Soon, an occasional drink came to buyibg a bottle of rum a week with the shopping. It's easy and sneaks up on you. One day, I said, " "You know what? Let's cut this out." We went off spirits altogether.
