Hi.How much time do I need to learn self defence so I m safe from professional assasins?

Answer 1

A "professional" will track your movements, then shoot you from a distance, blow you up in your car, or casually walk past you and turn and shoot you in the head. If a "professional" wants you dead, you are going to die.

Answer 2

All the time in worlds would not protect you from poisons, guns, and explosives. Maybe if your assassins are the gentlemanly type, fighting one-on-one, Marquess de Queensbury style, you might have a chance..

Answer 3

As much as your training suggests. No training = Many years. Bit of training still years, Daily training = one to two years.

Peace.

Answer 4

How much time you have left to live?

That is how long you have to learn!
