really sorry for that kind of gesture
No problem, you are not a troll after all, just a squid!
The ABS issue is fairly well covered here and in the other thread I gave you a link to.
Some swear by ABS, especially those who ride hard. I thought it was a great idea when I first saw it available as a modestly priced option. However on looking at ABS closer I don't see it as the game changer it was for cars
I would be tempted if the option was available on a bike to be used mainly on sealed road, but I don't see it as a biggie. Forget retrofitting.
On the helmet question; it is a good idea to wear one any time on the road, but riding in an environment similar to yours, I have little time for the MSF graduates mantra ATGATT.
I have never been able to get along with full face helmets, though if I was racing or riding hard on open roads and highways I would be inclined to get used to wearing one. I don't ride fast, but I noticed that when I was wearing a full face helmet my speed increased, and I was less aware of just how fast I was going, and the environment in general. I use an open face 3/4 helmet at home.
In relatively slow moving heavy traffic, in a hot environment a full face helmet is uncomfortable, and restricts peripheral vision and hearing. Any increase in protection has to be weighed against the disadvantages.
Here in Phuket, where I seldom go faster than about 65 km/hr, I wear a well fitting shortie helmet. It is comfortable and does not restrict my vision or hearing, but would protect the most vulnerable part of my head in an accident.
