Lotus Karate

Know any martial arts that focuses on counterattacks and techniques instead of speed and strength.?

I have heard that knowing martial arts that focus mostly on speed and strength fade and diminish as someone ages. I have just started out and have not learned any techniques yet, but if this is true, would learning techniques that create a lot of focused power that can smash bones be a waste of time if I cannot use them in my 50′s? Or should I just continue to practice karate and kickboxing? Also, if I ever have to face someone who is bigger, stronger, or faster than me, what kind of martial arts should I practice? I hear that Lotus Self Defense is pretty powerful. What should I do as a novice martial artist?

i would have to say go take jiu-jitsu and when you get older take aikido , but kickboxing is kicka** though
