Oh I've read very high marks about Singapore, including even intolerance for corruption. But also, very expensive for expats. English fluency is a plus. Decades ago I was a power shopper, but not in recent decades. I would be curious if there are any thrift shops like Goodwill here, those are an adventure for me, mostly fine cookware and cooking knives found dirt cheap. But we have that here.

The trips you've taken, Ron, those look really good, but like you say, if I can handle the heat and humidity down near sea level.

The mountainous areas of SEA look really good on a map and in photos, and better climate for me, but I don't kid myself about the ability to bike such terrain, not just at this age, but even younger. I'm not a stellar climber, I have to switch off between standing, grinding up in low, and walking, and that's for climbs of less than 1 km.

Jipe, you mentioned scuba. My good friend did his annual trip to SEA last winter, planned a lot of scuba, popped an eardrum on the flight, got medical attention, but scuba was definitely out. He rolled with the punches and changed his itinerary.
