OK, I have a problem eating healthy food, and I’ve always had a problem (understatement) sticking to my ideal weight, but I’ve been drinking lots of water (probably more than 4 liters a day), and I feel great. Something as trivial as cutting back on soft drinks and increasing water (and fruit juice) consumption really does make a big difference.
All parts should go together without forcing. You must remember that the parts
you are reassembling were disassembled by you. Therefore, if you can’t get
them together again, there must be a reason. By all means, do not use a hammer.
