Before getting back into the fishkeeping pastime almost 8 years ago now, I went into mad travelling mode.
Decided that since the body's ability to do stuff was declining I would go see the world....easiest and most leisurely way of doing that was small ship cruising. Thoroughly enjoyed a few years of longhaul cruises....the longest was 6 weeks with a week upfront in Singapore, cruising from there to Savona via Indonesia, Sri Lanka, India, Oman, Yemen, Jordan, Suez Canal, Egypt, Malta and then Savona Italy. Also sailed from Valparaiso to Buenos Aires via Cape Horn & Falklands, have sailed Vietnam, Hong Kong, Mainland China, Japan, Caribbean, Panama & Mexico, Iceland & Norway. A great way to see the world, often pretty expensive (especially when cruising solo as I did).
