Begin by standing on a comfort...

Begin by standing on a comfortable surface, where you have plenty of room at each side. With a 5-lb potato sack in each hand, extend your arms straight out from your sides and hold them there as long as you can. Try to reach a full minute, and then relax. Each day you'll find that you can hold this position for just a bit longer.
After a couple of weeks, move up to 10-lb potato sacks. Then try 50-lbpotato sacks and then eventually try to get to where you can lift a 100-lbpotato sack in each hand and hold your arms straight for more than a full minute. (I'm at this level.)
After you feel confident at that level, put a potato in each of the sacks.

DNA

In 1967, the first synthesis of biologically active DNA in a test tube was announced at a press conference by Arthur Kornberg who had worked with Mehran Goulian at Stanford and Robert L. Sinsheimer of MIT. Kornberg chose to replicate the relatively simple DNA chain of the Phi X174 virus, which infects bacteria (a bacteriophage). It has a single strand of DNA only about 5500 nucleotide building blocks long, and with about 11 genes, it was easier to purify without breaking it up. Having isolated the Phi X174 DNA, they used the DNA from E. coli, a common bacterium in the human intestine that could copy a DNA template from any organism. The viral DNA template thus copied was found to be able to infect bacteria - it was error-free, active DNA.*
