Have you ever had any problems using a fire extinguisher?
I’m currently doing a degree in design, and one of our projects is to re-design a product for use in an emergency situation, and improving the interaction design between user and object. I have chosen to redesign a fire extinguisher, as I believe these can be tricky to use at the best of times, let alone in a panic. The brief is mainly looking at designing the usability/interaction for a home-use extinguisher for the everyday person, so British Standards etc can be effectively ignored for now.
So yeah, just wondering if anyone’s experienced any problems that could be looked at/solved with my designs? It would help me out a great deal.
Pull pin, point, pull trigger design a pin that breaks when you pull the trigger but yet is visiable when walking by to see if the pin is still intact or not
What day is best for automatic purchases of mutual funds?
Has anyone done research to find out if there is an optimal day to make automatic purchases of mutual funds? Is the 2nd of the month better than the 18th? Is the 5th of the month better than the 25th?
I make monthly automatic purchases of mutual funds and I am just looking for the best day to choose. Does it make any real difference over 20 years or so?
The bottom line: If you have a choice in your monthly investing, schedule it for the close of the third-to-last trading day of each month. Similarly, if you have a lump sum to invest, this may well be the most propitious day to pull the trigger.
How do I choose the right weight so that i can see growth?
I’ve been weight lifting for three months now. I’m worried that I’m trying to lift too much and i may be affecting my form. How do i choose the right weight so that i can see change in time? How long does it take to see change? Especially the arms…
To trigger adaptive mechanisms in your body for growth you need to lift a minimum of 80% of your one-rep max for each exercise.
If you don’t know your max for each exercise, a weight that is very challenging to complete 10 reps is about 80%. A weight that you can do 5 reps is about 85% of your max.
Maintaining good form is important to effectively work the muscles you are targeting and for injury preventive. Once you are so fatigued that you can’t maintain good form, it is time to end the set and put the weight down.
For any new exercise, start very light and practice form. For instance, when learning how to squat, people start with an empty bar and a friend watches their form.
Once form is perfect, then pick a weight that you can do without any strain or fatigue doing 10 reps. Add 5 to 10 lbs of weight each workout until it get challenging to do 10 reps.
Thereafter, add 2.5 to 5 lbs a week to keep improving.
Work all the major muscles in your body for the best appearance and strength. Don’t just work the “show” muscles. Real strength=Overall strength.
Do exercises that work a lot of muscles at one time. For instance, pull-ups work the lats and biceps. An example whole body workout:
Squat or dead lift or lunge
leg curls or back extension
