Well I can't comment on everything on that list but some examples:
Train rides - Thai trains are not for fun.
Bike riding - in 35 C / 100 F temperatures? With the pollution included? I think I'll pass.
Motorbiking - On Thailand's death roads?
Temples - Seen one, seen them all.
Golf - Yeah, maybe when I'm 70.
I could list a bunch of things not available or pleasant to do in Thailand.
Of course Thailand offers things to do to fill one's time but are there better alternatives out there?
